The 2006-S Nebraska State Quarter is worth anywhere from $0.50 in typical proof condition to over $1,200 for rare, high-grade silver specimens. While most found in change are just worth face value, those with the “S” mint mark are special proof coins intended for collectors rather than circulation.

Coin Version	Condition / Grade	Estimated Value
2006-S Clad Proof	PR69 – PR70 Deep Cameo	$2.00 – $15.00
2006-S Silver Proof	PR69 – PR70 Deep Cameo	$12.00 – $45.00
2006-S Silver Proof	NGC/PCGS Top Pop	$100.00+

Understanding the 2006-S Nebraska Quarter Mint Mark

If you have found a quarter with a “Chimney Rock” design and a small “S” next to the ponytail of George Washington, you have found a San Francisco minted proof coin. Unlike the millions of quarters struck in Philadelphia (P) or Denver (D) for everyday spending, the 2006-S was specifically minted for collectors. If you are unsure about the origin of your coin, using a top coin identifier app can help you distinguish between the different mint marks and metal compositions.

The San Francisco Mint produced two distinct versions of the Nebraska quarter in 2006: the Cooper-Nickel (Clad) version and the 90% Silver version. The appearance of these coins is striking, featuring a mirror-like background and frosted details. Because they were sold in protective plastic sets by the U.S. Mint, finding one “in the wild” usually means someone spent a collector’s coin by mistake.

To get an instant answer on what you have, the CoinKnow app allows you to snap a photo and see the mint history. Whether it is an “S” for San Francisco or a “P” for Philadelphia, knowing the mint location is the first step in determining if you’ve found a treasure or just twenty-five cents.

Copper-Nickel vs. Silver: How to Tell the Difference

Not all 2006-S Nebraska quarters are made of the same material. This is the most crucial factor in determining the price. The “Clad” version is made of the same metals as standard quarters—a core of pure copper sandwiched between layers of copper and nickel. The “Silver” version is 90% silver and 10% copper.

The easiest way to check is to look at the edge of the coin. If you see a solid silver-colored edge, it is likely the silver version. If you see a copper stripe, it is the clad version. Another way is weight; silver quarters weigh 6.25 grams, while clad quarters weigh 5.67 grams. If you don’t have a scale, you can check the current market values for 2006 state quarters to see how much of a premium silver commands.

Composition Type	Weight (Grams)	Metal Content
Clad Proof	5.67g	Copper-Nickel
Silver Proof	6.25g	90% Silver

The Value of Nebraska Silver Proof Quarters

The 2006-S Silver Nebraska Quarter is highly sought after because of its precious metal content and its lower mintage compared to the clad version. In early 2006, the U.S. Mint released approximately 1.5 million silver proof sets containing this quarter. While that sounds like a lot, it is a tiny fraction of the hundreds of millions produced for circulation.

The value of these coins fluctuates with the spot price of silver. However, for a coin in “Deep Cameo” condition—where the contrast between the shiny background and the white frosted design is perfect—the collector value far exceeds the melt value. Collectors often look for “PR70” grades, which represent a perfect coin under 5x magnification.

If you are curious about how the silver Nebraska coin compares to other releases from that year, checking the 2006 Nebraska quarter pricing data is essential. You might find that your coin is worth a significant premium over its silver weight if the condition is flawless.

Grading and Condition: Why It Matters for Your Quarter

When we talk about “value,” we are usually talking about coins in pristine condition. Most 2006-S Nebraska quarters found in pocket change are considered “impaired proofs.” This means they have scratches, fingerprints, or have lost their mirror-like shine. Once a proof coin is handled and circulated, its value drops significantly, often to just a dollar or two for clad versions.

Professional grading services like PCGS or NGC use a 70-point scale. A 2006-S Nebraska quarter graded PR69 is common and affordable. However, a PR70 (a perfect coin) can fetch much higher prices at auction. For everyday Americans, the best way to preserve value is to keep the coin in its original mint packaging or a protective flip.

Using CoinKnow can assist you in identifying surface damage that might lower the grade. If you see tiny hairline scratches (often called “whizzing”), the coin’s value as a collectible is diminished. Professional collectors pay for perfection, so keep your coins clean and avoid touching the faces of the coin with your fingers.

Grade Level	Clad Value	Silver Value
Impaired (Circulated)	$0.25 – $0.50	$5.00 – $7.00
PR65 (Choice Proof)	$1.50	$12.00
PR69 (Near Perfect)	$5.00	$18.00
PR70 (Perfect)	$25.00	$50.00+

Nebraska Quarter Design: The “Cornhusker State” Symbolism

The reverse design of the 2006 Nebraska Quarter features Chimney Rock, a famous geological formation that served as a landmark for pioneers on the Oregon and Mormon Trails. Next to it is a horse-drawn covered wagon carrying pioneers, symbolizing the westward expansion and the rugged spirit of the state.

The design was created by Charles Vickers and was the 37th coin released in the 50 State Quarters Program. For locals in Nebraska, this coin is a point of pride, which can sometimes drive “nostalgia value” in local markets. While it might not be a $1,000 coin in standard condition, its historical significance makes it a staple of any State Quarter collection.

If you find a Nebraska quarter that looks “different”—perhaps the wagon is blurry or the date is doubled—you might have an error coin. Use the CoinKnow app to cross-reference known errors for the 2006 series. Error coins are the “wild cards” of the hobby and can turn a regular quarter into a high-value item.

Rare Errors to Look For in 2006 Quarters

While major errors are rare on proof coins because the U.S. Mint has stricter quality control for the San Francisco facility, they are not impossible. Collectors keep an eye out for “Double Dies.” This happens when the hub strikes the die incorrectly, creating a ghost-like doubling effect on the lettering or the design elements.

Another rare occurrence is a “Mismatched Die” error, though none have been significantly confirmed for the 2006-S Nebraska specifically. Most errors found by everyday people are actually on the P and D mint quarters, such as the famous “Extra Leaf” Nebraska quarter, which was actually a myth (the “Extra Leaf” was on the Wisconsin quarter), but Nebraska has its own minor die chips and cracks.

If you suspect your 2006-S Nebraska quarter has a unique mistake, don’t clean it! Cleaning a coin with chemicals or clothes will instantly destroy its numismatic value. Instead, take high-resolution photos and consult a professional or a community forum to see if you’ve discovered a new variety.

Potential Error Type	Description	Estimated Value
Doubled Die Reverse	Doubling on ‘Nebraska’ or ‘1867’	$20 – $100
Off-Center Strike	Part of the design is missing	$50 – $200
Die Crack (Cud)	Raised line of metal on the surface	$5 – $15

FAQ

Q: Why does my 2006-S Nebraska quarter look so shiny compared to other quarters?

A: Your coin is likely a “Proof” coin. These are made using polished blanks and special dies struck at least twice to create a high-contrast, mirror-like finish. They are usually sold in sets and not intended for circulation.

Q: How much is a Nebraska quarter with a “P” or “D” mint mark worth?

A: Quarters with the “P” (Philadelphia) or “D” (Denver) mint marks were made for general circulation. Unless they are in absolutely perfect “Mint State” (MS67 or higher) or have a major error, they are only worth their face value of $0.25.

Q: Is every “S” mint mark quarter made of silver?

A: No. The San Francisco mint produced both Clad (copper-nickel) and Silver versions in 2006. You must check the edge of the coin or weigh it to be sure. Silver quarters have no copper stripe on the edge.

Q: Should I get my 2006-S Nebraska quarter professionally graded?

A: Only if you believe it is a “Perfect 70” or a very rare silver variety. Grading costs can range from $20 to $50 per coin, so if the coin’s market value is only $10, it is not worth the expense.

Q: Where can I sell my 2006-S Nebraska quarter?

A: Local coin shops are great for quick cash, but they may offer less than the full market value. For higher-end silver proofs, online auction sites or specialized coin communities often yield the best prices.
