1999 Quarter Coin Value: How Much Is It Worth?

1999 Quarter Coin Value: How Much Is It Worth?

The 1999 quarter launched the 50 States Quarters program with five different reverse designs: Delaware, Pennsylvania, New Jersey, Georgia and Connecticut. Guide estimates for the versions listed below range from about $0.93 at MS60 for business strikes up to $43.00 at PR65 for silver proofs.

Which part of that range applies depends entirely on your coin's mint, reverse design, condition and whether it is a standard clad or silver proof issue.

Which 1999 Quarter Versions Are Worth Money?

  • S-mint silver proofs (Delaware, Pennsylvania, New Jersey, Georgia, Connecticut) carry guide estimates around $43.00 at PR65 — significantly above the clad versions.
  • S-mint clad proofs are estimated around $10.00 at PR65 per the guide, so confirming clad versus silver composition matters.
  • Business strikes in original MS65 condition are estimated around $6.25 by the guide — well above face value for a coin that usually circulates.
  • Check your coin's weight and edge to separate a silver proof from a clad proof before assuming either value.

Step 1: Identify Your 1999 Quarter Mint Mark and Version

1999 Quarter: Mint & Version Guide with all listed versions and genuine identifying details

1999 Washington 50 States Quarters version comparison

Start with the obverse. Look near Washington's ponytail for a small mintmark: P for Philadelphia, D for Denver, or S for San Francisco.

Then flip the coin and identify which state reverse you have — Delaware, Pennsylvania, New Jersey, Georgia or Connecticut. Each combination of mint and reverse is a separate version with its own value.

All business-strike 1999 quarters are copper-nickel clad, weighing about 5.67 grams and measuring 24.26 mm across. S-mint proofs come in two compositions: a clad version (same 5.67 g) and a heavier silver proof (90% silver, about 6.25 g).

You cannot reliably tell them apart by sight alone. Weigh the coin, or check its edge — a silver proof will not show a copper-colored stripe.

Don't confuse a statehood date shown on the reverse with the minting year. The date on the obverse near Washington's portrait is what matters.

And remember: a proof finish or a particular mintmark is an intentional variety, not an error.

Step 2: Check Your 1999 Quarter Grade

1999 undefined numeric grading guide

Focus on Washington's cheek and the hair above his ear — those areas wear first. On a lightly circulated coin, you will see slight flattening there before anything else softens.

A coin that still shows full original mint luster with no wear is in Mint State territory.

For proofs, examine the mirror-like fields under good light. Hairlines from improper handling and haze from storage reduce the grade even if the devices look sharp.

Compare your coin to the reference image for the same type; don't mix a business-strike grading standard with a proof coin.

A weak strike can make an unworn coin look like it has wear. If the high points are soft but the surrounding fields still carry full luster, you may have a strike issue rather than actual circulation damage.

Luster and wear must be evaluated together.

Step 3: Check 1999 Quarter Value by Mint and Version

1999 Quarter — P — Delaware — regular strike

1999 Quarter Coin — P — Delaware — regular strike, obverse and reverse, with date and mint-location details

The 1999-P Delaware quarter is a copper-nickel clad business strike weighing about 5.67 grams. Millions were produced for everyday commerce, so circulated examples are worth face value.

What pushes one above 25 cents is original, undamaged condition.

USA Coin Book estimates about $0.93 at MS60 and $6.25 at MS65. Those grades are not guaranteed offers — they represent guide-level retail estimates for coins in that specific condition.

Look for full luster with no bag marks or contact damage to approach the higher figure.

1999 Quarter — D — Delaware — regular strike

1999 Quarter Coin — D — Delaware — regular strike, obverse and reverse, with date and mint-location details

Denver's 1999-D Delaware quarter shares the same copper-nickel clad composition and design as the Philadelphia version. Worn examples circulate at face value.

High-grade pieces are the ones collectors notice.

Guide estimates from USA Coin Book place this at about $0.93 in MS60 and $6.25 in MS65. To distinguish it from the P mint, check the mintmark near Washington's ponytail — a small "D" confirms Denver production.

Original luster and clean fields are what move a coin toward the upper estimate.

1999 Quarter — S — Delaware — clad proof

1999 Quarter Coin — S — Delaware — clad proof, obverse and reverse, with date and mint-location details

The 1999-S Delaware clad proof was struck at San Francisco for collectors, using the same copper-nickel clad composition as the business strikes. Proofs feature mirror-like fields and frosted raised designs.

Confirm the composition by checking the edge or weighing the coin before assuming a silver proof value.

USA Coin Book estimates this clad proof at about $10.00 in PR65. That is well below the silver version, so getting the composition right matters.

Look for clean, haze-free fields and sharp device edges.

1999 Quarter — S — Delaware — silver proof

1999 Quarter Coin — S — Delaware — silver proof, obverse and reverse, with date and mint-location details

The 1999-S Delaware silver proof is struck in 90% silver with 10% copper, weighing approximately 6.25 grams — noticeably heavier than the 5.67 g clad version. It carries the S mintmark and shows the same proof finish with reflective fields and frosted devices.

USA Coin Book estimates it at about $43.00 in PR65, making it one of the higher-valued regular versions for this year. Confirm silver content by weight or by examining the edge, which should lack the copper stripe visible on clad coins.

Original government packaging is another good indicator.

1999 Quarter — P — Pennsylvania — regular strike

1999 Quarter Coin — P — Pennsylvania — regular strike, obverse and reverse, with date and mint-location details

The 1999-P Pennsylvania quarter features the Commonwealth's Keystone State reverse design. It is copper-nickel clad, 24.26 mm in diameter, weighing about 5.67 grams.

Circulated examples are common and trade at face value.

In uncirculated condition, USA Coin Book estimates about $0.93 at MS60 and $6.25 at MS65. These are guide estimates, not guaranteed offers.

Check for original luster, minimal bag marks and a sharp strike on the reverse design elements to gauge condition.

1999 Quarter — D — Pennsylvania — regular strike

1999 Quarter Coin — D — Pennsylvania — regular strike, obverse and reverse, with date and mint-location details

Denver produced its own run of the 1999 Pennsylvania quarter in the same copper-nickel clad composition. The D mintmark appears on the obverse near Washington's hair.

Worn coins are worth 25 cents.

Guide estimates sit at about $0.93 for MS60 and $6.25 for MS65 per USA Coin Book. The reverse design is identical to the P-mint version, so the mintmark is your only distinguishing feature.

Look for fully lustrous surfaces with minimal contact marks if you think yours might be uncirculated.

1999 Quarter — S — Pennsylvania — clad proof

1999 Quarter Coin — S — Pennsylvania — clad proof, obverse and reverse, with date and mint-location details

San Francisco produced a clad proof version of the 1999 Pennsylvania quarter for collector sets. Same copper-nickel clad composition as the business strikes, but with proof-quality mirror fields and frosted devices.

USA Coin Book estimates this at about $10.00 in PR65. Do not confuse it with the silver proof, which weighs more and carries a significantly higher guide value.

Weigh it or inspect the edge to confirm clad composition before referencing this estimate.

1999 Quarter — S — Pennsylvania — silver proof

1999 Quarter Coin — S — Pennsylvania — silver proof, obverse and reverse, with date and mint-location details

The 1999-S Pennsylvania silver proof is a 90% silver coin weighing about 6.25 grams. It features the same proof finish — reflective fields, frosted devices — as the clad proof, but the composition and value are quite different.

USA Coin Book estimates about $43.00 at PR65. That premium over the $10.00 clad proof is why confirming silver content matters.

Check the coin's edge for a uniform silver appearance rather than a visible copper layer, or weigh it to see if it comes in near 6.25 grams versus the clad's 5.67 grams.

1999 Quarter — P — New Jersey — regular strike

1999 Quarter Coin — P — New Jersey — regular strike, obverse and reverse, with date and mint-location details

The 1999-P New Jersey quarter shows Washington crossing the Delaware on its reverse. It is copper-nickel clad, standard diameter, and weighs about 5.67 grams.

Circulated pieces are common.

USA Coin Book estimates about $0.93 at MS60 and $6.25 at MS65. These guide estimates apply to original, unimpaired coins in those specific grades.

If your coin has been cleaned or shows obvious wear, it falls below these figures. The P mintmark on the obverse confirms Philadelphia production.

1999 Quarter Coin — D — New Jersey — regular strike, obverse and reverse, with date and mint-location details

The Denver-minted 1999-D New Jersey quarter is the same copper-nickel clad composition and design, just with a D mintmark. Most circulated examples are face-value coins.

Guide estimates from USA Coin Book are about $0.93 at MS60 and $6.25 at MS65. These are retail guide figures.

To reach MS65, a coin needs full luster, a clean strike and only very minor contact marks that don't distract from the design. Check the mintmark carefully — the D and P can be subtle on this series.

1999 Quarter — S — New Jersey — clad proof

The 1999-S New Jersey clad proof was produced for collector proof sets. It has the same copper-nickel clad composition as business strikes but features proof-quality reflective fields.

The S mintmark confirms San Francisco.

Coin Value Lookup is a useful place to look up guides for each state quarter version side by side, so you can compare clad proof and silver proof values quickly.

USA Coin Book estimates this clad proof at about $10.00 in PR65. Confirm you have the clad version — not the heavier silver proof — before using this figure.

1999 Quarter Coin — S — New Jersey — silver proof, obverse and reverse, with date and mint-location details

The 1999-S New Jersey silver proof is struck in 90% silver and weighs approximately 6.25 grams. It carries the same S mintmark and proof finish as the clad version but has a noticeably different edge appearance and weight.

USA Coin Book estimates about $43.00 at PR65. Silver proof quarters from 1999 were sold in special silver proof sets, so original packaging is a strong clue.

Without packaging, weighing the coin is the most reliable way to separate it from the $10.00 clad proof version.

The 1999-P Georgia quarter carries the Peach State reverse design. Copper-nickel clad, 24.26 mm, about 5.67 grams.

Most circulated examples sit at face value, as production was very high.

USA Coin Book estimates about $0.93 at MS60 and $6.25 at MS65. The P mintmark on the obverse near Washington's ponytail identifies Philadelphia production.

For the MS65 estimate to be relevant, the coin should show full original mint luster with only the faintest contact marks.

Guide estimates from USA Coin Book are about $0.93 at MS60 and $6.25 at MS65. These are not guaranteed sale prices — they are retail guide estimates for coins at those grades.

A sharp, fully lustrous coin with minimal marks is what you need to approach the upper figure.

The 1999-S Georgia clad proof has reflective fields and frosted design elements, struck at San Francisco in the same copper-nickel clad composition as the business strikes. Don't confuse it with the heavier silver proof.

USA Coin Book estimates about $10.00 at PR65 for this clad version. Weigh the coin or check the edge to confirm it is clad before assigning this value.

A copper stripe visible along the edge is a clear clad indicator.

1999 Quarter — S — Georgia — silver proof

1999 Quarter Coin — S — Georgia — silver proof, obverse and reverse, with date and mint-location details

The 1999-S Georgia silver proof is struck in 90% silver, weighing about 6.25 grams. It looks very similar to the clad proof, with the same mirror fields and frosted design, but the composition sets it apart.

USA Coin Book estimates about $43.00 at PR65. Silver proofs from 1999 were sold in dedicated silver proof sets from the Mint.

If yours came from one of those sets, you likely have the silver version, but confirming by weight or edge inspection is always a good idea.

The 1999-P Connecticut quarter features the Charter Oak on its reverse. Standard copper-nickel clad composition, 24.26 mm, about 5.67 grams.

Like the other 1999 P-mint state quarters, circulated examples are extremely common.

USA Coin Book estimates about $0.93 at MS60 and $6.25 at MS65. Those guide figures apply only to uncirculated coins at those specific grades.

A worn Connecticut quarter from pocket change is still just a quarter.

1999 Quarter — D — Connecticut — regular strike

1999 Quarter Coin — D — Connecticut — regular strike, obverse and reverse, with date and mint-location details

The 1999-D Connecticut quarter shares the same reverse design and copper-nickel clad composition as the Philadelphia version. The D mintmark near Washington's hair ribbon is the distinguishing feature.

Guide estimates from USA Coin Book place it at about $0.93 for MS60 and $6.25 for MS65. Full, unbroken mint luster and minimal bag marks are what separate a $6+ coin from a face-value one.

Check both sides under good light before making a grade call.

1999 Quarter — S — Connecticut — clad proof

1999 Quarter Coin — S — Connecticut — clad proof, obverse and reverse, with date and mint-location details

San Francisco struck a clad proof version of the 1999 Connecticut quarter for collector proof sets. It has the S mintmark and shows the characteristic proof contrast between reflective fields and frosted devices.

USA Coin Book estimates about $10.00 at PR65. That is the clad version — not the more valuable silver proof.

Check the coin's weight or edge before comparing to a value chart. Clean, hairline-free fields are what earn the PR65 grade.

1999 Quarter — S — Connecticut — silver proof

1999 Quarter Coin — S — Connecticut — silver proof, obverse and reverse, with date and mint-location details

The 1999-S Connecticut silver proof is 90% silver and 10% copper, weighing approximately 6.25 grams. It carries the same proof finish as the clad version but is worth considerably more.

USA Coin Book estimates about $43.00 at PR65. That is the highest guide estimate among the regular Connecticut quarter versions.

To confirm you have the silver rather than the clad proof, weigh the coin — the silver version is roughly 0.6 grams heavier — or examine the edge for the absence of a copper stripe.

1999 Quarter Error List

1. 1999 Quarter — Delaware — Off-Center Strike

An off-center strike on a 1999 Delaware quarter occurs when the planchet is not properly seated between the dies at the moment of striking. The result is a portion of the design shifted to one side, leaving an unstruck crescent of blank metal on the opposite edge.

The degree of misalignment — measured as a percentage — and whether the date and mintmark remain visible both affect desirability.

Do not confuse this with a clipped planchet, which removes part of the blank before striking, or with one-sided die misalignment where the design is weak rather than displaced. Post-mint flattening from a vise or other tool can mimic parts of this look but will not produce a genuine unstruck crescent with proper metal flow.

Condition, the percentage off-center and overall eye appeal all influence value individually.

2. 1999 Quarter — Delaware — Doubled Die Obverse

A doubled die obverse has been reported on the 1999-S Delaware quarter. This variety shows consistent doubling on obverse design elements — letters, date or portrait features — caused during the die-making process.

Under magnification, look for separation or notching on affected elements that remains uniform across the entire design area rather than appearing as a flat, shelf-like distortion.

Machine doubling is the most common lookalike. It produces flat, shelf-like displacement rather than the rounded, separated profiles of a true doubled die.

Reflections under certain lighting can also mimic doubling to the naked eye. Compare your coin side by side with a known normal example under the same light source.

The specific visibility and condition of the doubling will determine how much collector interest it attracts.

3. 1999 Quarter — Georgia — Doubled Die

A doubled die variety has been reported on the 1999 Georgia quarter. This affects the design with consistent doubling visible on certain elements.

True doubled dies show uniform separation or notching in the affected areas, and the effect appears the same regardless of how you tilt the coin under light.

Machine doubling — a far more common occurrence — looks like flat, shelf-like displacement and generally does not carry a significant premium. Reflections on proof surfaces or post-mint impressions from contact with other coins can also mimic doubling.

Examine the coin under steady magnification and compare against a confirmed normal example. The value of any doubled die depends on the strength and visibility of the doubling as well as the coin's overall condition.

4. 1999 Quarter — Georgia — Off-Center Strike

Off-center strikes have been reported on the 1999 Georgia quarter. The design appears shifted, leaving a crescent of blank, unstruck metal along one edge.

Collectors generally prefer examples where the date and mintmark are still visible, since those are identifiable and attributable.

The percentage of the off-center shift matters. A coin that is 5% off-center looks mildly odd; one that is 50% off-center with a visible date is a dramatic error.

Do not confuse this with a clipped planchet — clips occur before striking and remove a portion of the blank, while an off-center strike shifts the entire design on a full-size planchet. Post-mint flattening or damage will not show proper unstruck metal texture.

Value depends on the degree, date visibility and coin condition.

5. 1999 Quarter — Georgia — Missing Clad Layer

A missing clad layer has been reported on the 1999 Georgia quarter. When one of the outer clad layers is absent from the planchet before striking, the exposed surface may appear a different color — possibly showing the copper core — and the coin's weight will be noticeably below the standard 5.67 grams.

Weigh your coin and compare the edge to a normal clad quarter. A genuine missing clad layer will reduce the weight and often show a uniform color difference on the affected side.

Toning, environmental damage, corrosion and chemical cleaning can all change a coin's surface color without actually removing a clad layer. Acid-treated coins sometimes look similar but will show irregular pitting or surface roughness.

Condition, the extent of the missing layer and overall eye appeal all factor into what a collector would pay.

6. 1999 Quarter — Connecticut — Off-Center Strike

Off-center strikes have been reported on the 1999 Connecticut quarter. The design is displaced from center, leaving a blank crescent along one edge.

The more dramatic the shift — while still preserving a visible date and mintmark — the more collector interest it generates.

A clipped planchet is the most common lookalike, but clips remove part of the blank before striking, producing a different edge profile and often a weakness on the opposite side. Post-mint damage from machinery or tools can flatten one side but will not produce the characteristic unstruck crescent with smooth, original planchet surface texture.

Value depends on the percentage of misalignment, date visibility and the coin's preservation.

7. 1999 Quarter — Pennsylvania — Off-Center Strike

An off-center strike has been reported on the 1999 Pennsylvania quarter. This means the planchet was misaligned when the dies came together, shifting the design and leaving an unstruck crescent of blank metal.

The shift can range from barely noticeable to dramatically off.

Check that the crescent area has the smooth, original planchet surface rather than tool marks or post-strike damage. One-sided die misalignment — where the design is weak on one side but not actually displaced — is a different issue and generally less dramatic.

A genuine off-center with a visible date and mintmark draws more collector attention than one where identifying information is cut off. Condition and the percentage of misalignment influence value.

8. 1999 Quarter — Pennsylvania — Clipped Planchet

A clipped planchet error has been reported on the 1999 Pennsylvania quarter. This occurs when the blank is punched from strip metal that overlaps a previously punched hole, resulting in a missing curved section.

The clip happens before striking, so the coin's design often shows weakness opposite the clip where metal could not flow completely into the die.

Look for a smooth, curved missing section with the original planchet edge texture — not a rough or filed edge. An edge that has been cut, filed or corroded after minting will usually show tool marks, irregular surfaces or corrosion pitting.

A genuine clip will also produce a characteristic "Blakesley effect" — a weak area of the rim directly opposite the clip. The size of the clip and overall coin condition affect collector interest.

9. 1999 Quarter — New Jersey — Clipped Planchet

A clipped planchet has been reported on the 1999-D New Jersey quarter specifically. The clip is a missing portion of the blank that occurred before the coin was struck, resulting in an incomplete edge and often a corresponding weak area on the rim opposite the clip.

To verify, examine the missing section's edge. It should be smooth and consistent with original planchet metal, not rough, filed or corroded.

A genuine clip typically causes a weakness on the opposite rim — the Blakesley effect — which helps confirm the error. Post-mint edge damage from tools or corrosion can mimic a clip but will lack the characteristic metal-flow weakness on the opposite side.

The size of the clip and the coin's condition determine collector value.

10. 1999 Quarter — New Jersey — Wrong Planchet / Off-Metal Strike

A 1999-P New Jersey quarter struck on a wrong planchet has been reported — specifically described as struck on a 5-cent planchet. This type of error occurs when a blank intended for a different denomination enters the quarter press.

The resulting coin would show the quarter's design but on an incorrectly sized and weighted blank.

To evaluate, measure the coin's weight, diameter and edge characteristics and compare them against both a normal quarter and the reported planchet type. A genuine wrong-planchet strike will produce an incomplete or undersized design because the blank is smaller than what the dies expect.

Plating, corrosion, acid treatment or deliberate alteration can change a coin's appearance in ways that mimic an off-metal strike. Professional authentication is typically recommended for this category.

11. 1999 Quarter — Delaware — Rotated Dies

A rotated die error has been reported on the 1999 Delaware quarter. On a normally aligned US coin, flipping it top to bottom should show the reverse design properly oriented.

When one die is rotated relative to the other during production, the reverse appears tilted or even upside-down compared to the obverse.

To check, hold the obverse upright and flip the coin along its vertical axis (top to bottom, like turning a page). If the reverse is not properly oriented, you may have a rotation.

The degree of rotation matters — small rotations are less dramatic, while a full 180-degree rotation is the most extreme. Do not confuse this with a photograph that has been digitally rotated or a coin simply turned sideways in a holder.

Value varies with the degree of rotation and overall condition.

12. 1999 Quarter — Georgia — Rotated Dies

A rotated die error has been reported on the 1999-D Georgia quarter, with one reported example showing approximately 135 degrees of rotation. That is a severe misalignment where the reverse appears nearly upside-down relative to normal coin orientation.

To test your coin, hold the obverse right-side up and flip it top to bottom. The reverse should also appear right-side up on a normal coin.

If the reverse is rotated significantly — 30 degrees or more is generally noticeable — you may have this error. Slight rotations of a few degrees are sometimes found and are less sought after.

Photographs can appear rotated if the image was flipped, so always test with the physical coin. Condition and the degree of rotation both influence value.

13. 1999 Quarter — Delaware — Missing Clad Layer

A missing clad layer has been reported on the 1999 Delaware quarter. This error means one of the outer clad layers was absent from the planchet before striking, exposing a different-colored surface.

The coin's weight will be measurably lower than the standard 5.67 grams for a normal clad quarter.

Weigh the coin as a first step. A missing clad layer typically produces a uniform color change on the affected side — the exposed surface may appear copper-toned.

Toning, environmental damage, corrosion or chemical cleaning can all alter a coin's surface color and fool the eye. Look for a smooth, consistent color with proper design sharpness rather than pitting, roughness or uneven patches.

The extent of the missing layer and the coin's overall condition affect collector interest.

14. 1999 Quarter — Die Cap / Capped-Die Strike

A die cap error has been reported on the 1999-P Washington quarter series. A die cap forms when a struck coin sticks to one of the dies and is not ejected.

Subsequent blanks are then struck through that stuck coin, and the stuck coin itself becomes progressively cupped and distorted as it wraps around the die.

The result is a coin that appears cupped or bowl-shaped, with one side showing a normal design and the other showing a spread, distorted mirror image. Do not confuse this with a coin that has been bent by a vise or tool — post-mint bending will not produce a genuine incuse mirror impression from a die.

A normal weak strike also lacks the cupping and design transfer. These are dramatic errors and typically require professional authentication.

Value depends on the extent of the cap, condition and visual impact.

15. 1999 Quarter — Pennsylvania — Doubled Die Obverse

A doubled die obverse has been reported on the 1999-S Pennsylvania clad proof quarter. This variety shows consistent separation or notching on obverse design elements created during the die-manufacturing process.

On a proof coin, the doubled features may be especially visible because the sharp strike and reflective fields provide high contrast.

Compare the obverse lettering and date with a known normal 1999-S Pennsylvania proof under matching lighting. True doubling will show the same separation from multiple angles.

Machine doubling — which is mechanical displacement during the strike rather than a die variety — produces a flat, shelf-like effect and generally carries no premium. Reflections on proof surfaces can also trick the eye.

Magnification and consistent comparison are the best tools. Condition and the strength of the doubling determine collector interest.

16. 1999 Quarter — Double / Multiple Strike

A double-struck or multiple-struck error has been reported on the 1999-P quarter. This occurs when a coin receives two or more impressions from the dies, and the coin shifts between strikes.

The result is two separate, overlapping design impressions that are visually displaced or rotated relative to each other.

This is not the same as a doubled die, which is a single strike from a die that was made with doubling. A double strike shows two distinct, complete (or nearly complete) impressions of the entire design.

Look for clearly separated outlines of letters, the portrait or the rim that could not have been produced by a single impact. Post-mint impressions from being pressed against another coin will lack proper strike definition.

These dramatic errors attract serious collector attention. Value depends on the degree of displacement and overall condition.

17. 1999 Quarter — Delaware Spitting Horse Die Gouge

The 1999-P Delaware quarter has a well-known die crack variety sometimes called the "Spitting Horse." This shows as a raised line or blob of extra metal on the reverse, near the horse's mouth area, caused by a crack or chip in the die that filled with metal during striking. The result is a small raised feature that looks like the horse is spitting.

Die cracks produce raised lines because they are depressions in the die surface that fill with metal. An incuse scratch — cut into the coin's surface — is the opposite: it goes into the metal rather than rising above it.

Corrosion or foreign material stuck to the surface can also create raised bumps but will lack the linear, consistent shape of a genuine die crack. Examine the feature under magnification to confirm it is raised and consistent with a die origin.

18. 1999 Quarter — Delaware Spitting Horse Die Gouge

Also associated with the 1999-P Delaware quarter's "Spitting Horse" nickname, a die gouge in this area produces a raised blob or irregular lump of extra metal on the reverse near the horse. This results from damage to the die surface — a chip or gouge rather than a crack — that allows metal to fill the void during striking.

The distinction between a die crack (a linear fracture) and a die gouge (a more localized, irregular depression in the die) is subtle. Both produce raised features on the struck coin.

Compare the shape: a crack tends to be linear; a gouge tends to be a rounder blob. Incuse scratches, surface corrosion or adhesions from foreign material are common lookalikes but will not show the raised, consistent profile of a die-origin feature.

Check under magnification alongside a normal comparison coin.

19. 1999 Quarter — Connecticut — Brockage

An obverse brockage error has been reported on the 1999 Connecticut quarter. A brockage occurs when a previously struck coin fails to eject and gets pressed into the next blank.

The result is one side with a normal design and the other side with an incuse (sunken), mirror-image impression of the design from the stuck coin rather than from the die itself.

The key diagnostic is direction and depth. A brockage impression is incuse and reversed — a mirror image.

A die clash, which is a much more common occurrence, shows faint design elements transferred between the dies themselves and appears as shallow, ghostly outlines rather than a deep incuse impression. A coin pressed against another coin after minting can look similar but typically lacks the uniform depth and consistent pressure of a genuine brockage.

Professional authentication is advisable for this error type.

20. 1999 Quarter — Delaware — Wrong Planchet / Off-Metal Strike

A wrong-planchet strike has been reported on the 1999 Delaware quarter. This means the coin was reportedly struck on a blank intended for a different denomination or composition.

The resulting coin would display the Delaware quarter design but on a planchet of incorrect size, weight or metal.

To investigate, measure the coin's weight and diameter precisely and compare against the standard 5.67 grams and 24.26 mm for a normal clad quarter. A genuine wrong-planchet strike will typically show an incomplete or undersized design if the blank was smaller than expected.

Plating, acid treatment, corrosion or deliberate alteration can change a coin's appearance and weight in ways that imitate an off-metal error. Professional authentication is strongly recommended for any suspected wrong-planchet coin, as these are rare and frequently counterfeited or misidentified.
