The 1999-S Georgia State Quarter is worth anywhere from $1 in standard clad proof condition to over $2,500 for rare silver errors in high grades. If you have just discovered one of these peaches-and-oak-leaves coins in your change or an old collection, you might be curious if you are holding a hidden treasure.

Determining the Value of 1999-S Georgia Quarters

The Georgia quarter was the fourth coin released in the historic 50 State Quarters Program, and the “S” mint mark indicates it was produced at the San Francisco Mint. Unlike the millions of quarters made in Philadelphia or Denver for everyday spending, these coins were specifically struck for collectors. The value of your 1999-S Georgia quarter depends heavily on whether it is made of copper-nickel clad or 90% silver. If you are unsure exactly which variety you have, using a top coin identifier app can quickly clear up the confusion by analyzing the coin’s physical characteristics through a simple photo.

Most clad proofs you find in original packaging are worth between $1 and $5. However, the silver versions are much more desirable. To spot a silver quarter, look at the edge of the coin; if you see a solid silver color without a copper-colored “sandwich” stripe, you likely have the silver variety. These silver quarters generally trade for $10 to $35 depending on the quality of the strike and the preservation of the mirrored surfaces. Collectors often use the CoinHix app to track real-time market fluctuations for these specific silver issues.

Clad vs Silver Proof Varieties and Price Chart

Understanding the distinction between the two versions of the 1999-S Georgia quarter is essential for any amateur collector. The San Francisco Mint struck 3,713,359 clad proof quarters and 804,565 silver proof quarters. Because the silver mintage is significantly lower, those coins naturally command a higher premium. Furthermore, the condition, or “grade,” is the ultimate factor in pricing. Coins are graded on a scale of 1 to 70, with PR69 and PR70 being the most common grades for these modern proofs.

A standard 1999-S clad quarter in PR70 Deep Cameo (perfect condition) might sell for $20 to $30. In contrast, the silver version in a perfect PR70 grade can reach much higher figures. You can check the current 1999 state quarter price data to see how the Georgia issue compares to other early releases like Delaware or Pennsylvania. Below is a breakdown of what you can expect to pay or receive for these coins in today’s market.

Coin Variety	Grade (Condition)	Estimated Market Value
1999-S Georgia Clad Proof	PR65 to PR68	$1.00 – $4.00
1999-S Georgia Clad Proof	PR69 Deep Cameo	$8.00 – $12.00
1999-S Georgia Clad Proof	PR70 Deep Cameo	$25.00 – $35.00
1999-S Georgia 90% Silver Proof	PR69 Deep Cameo	$15.00 – $22.00
1999-S Georgia 90% Silver Proof	PR70 Deep Cameo	$45.00 – $65.00

Identifying Rare Errors on the Georgia State Quarter

While most 1999-S quarters are consistent in quality because they were handled with care by the Mint, some rare errors can make a coin worth a small fortune. One of the most famous errors involving the 1999 series is the “mule” error, where a state quarter design was accidentally paired with the wrong obverse or struck on a different coin’s planchet. For example, some 1999 Georgia quarters have been found struck on experimental planchets intended for the Sacagawea Dollar. These coins have a distinct golden tint and can sell for over $10,000 at auction.

Other common errors include off-center strikes, double dies, or clipped planchets. If you see something “funky” about your coin—like the text appearing twice or a portion of the design missing—do not spend it! These anomalies are exactly what high-end collectors look for. Many users have found these rare pieces by using the CoinHix app to scan their loose change. Comprehensive catalogs for 1999 Georgia quarter value trends often highlight these rare auction records to help you understand the potential upside of error hunting.

How to Care for Your Proof State Quarters

Since the 1999-S Georgia quarter is a “Proof” coin, its value is tied directly to its visual appeal. Proof coins are struck twice with specially polished dies to create a “Deep Cameo” effect, where the design (The Peach and Oak Sprays) looks frosted and sits against a mirror-like background. If you handle the coin with your bare hands, the oils from your skin can cause permanent smudges or “toning” that reduces the grade and value.

If you find a 1999-S quarter in a plastic holder or a Mint Set, leave it there! If it is already loose, handle it only by the edges and store it in a PVC-free coin flip or a hard plastic capsule. Protecting the “S” mint mark coin from environmental damage ensures that it maintains its value over time. If you are building a full set of all 50 states, keeping a digital inventory on CoinHix is a great way to stay organized and monitor the total worth of your collection as you add more coins.

Frequently Asked Questions About 1999-S Quarters

Q: How can I tell if my 1999-S Georgia quarter is silver?

A: The easiest way is to look at the edge (the “third side”) of the coin. If the edge is solid silver throughout, it is the 90% silver variety. If you see a copper or brownish stripe running through the middle of the edge, it is a standard copper-nickel clad coin. Additionally, silver quarters weigh more (6.25 grams) than clad quarters (5.67 grams).

Q: Can I find a 1999-S Georgia quarter in my pocket change?

A: It is rare, but possible. Occasionally, someone will break open a proof set and spend the coins as if they were regular quarters. These are called “impaired proofs.” Because they have been circulated, they usually have scratches and lose their mirror finish, making them worth only their face value of 25 cents or perhaps a small premium to a local collector.

Q: What is a PR70 Deep Cameo coin?

A: PR70 is the highest grade a coin can receive, meaning it is perfect even under 5x magnification. “Deep Cameo” (DCAM) refers to the strong contrast between the frosted design and the reflective background. A 1999-S Georgia quarter in this condition is highly prized by registry set collectors.

Q: Why is the Georgia quarter significant in the 50 State Quarters series?

A: Georgia was the fourth state admitted to the Union (January 2, 1788), which is why it was the fourth coin released in 1999. It features the state’s signature peach, oak sprigs, and the state motto “Wisdom, Justice, Moderation.” It remains one of the most popular designs in the entire ten-year series.
