The 1999-S Georgia State Quarter is worth anywhere from $3 in standard proof condition to over $500 for high-grade silver versions. While most of these coins found in change are only worth their face value, the “S” mint mark signifies a special production that catches the eye of collectors everywhere.
Where To Find the 1999-S Georgia Quarter and Why the Mint Mark Matters
If you have found a Georgia quarter with a small “S” located to the right of George Washington’s ponytail, you have stumbled upon a proof coin. Unlike the millions of quarters struck in Philadelphia or Denver for daily commerce, the San Francisco Mint produced these specifically for collectors. These coins were never intended to spend at the grocery store, yet they often find their way into circulation when old collections are broken up.
Because these quarters are struck using specially polished dies and planchets, they possess a mirror-like finish that makes the peach and the sprigs of live oak on the reverse side pop. If you aren’t sure if your coin is a proof or just a very shiny business strike, you can use a top coin identifier app to get an instant visual confirmation. Many people find that using the CoinKnow app helps them distinguish between the different finishes found on 1999 coinage.

In 1999, the Mint released the Georgia quarter as the fourth coin in the historic Statehood Quarters Program. This was a transition year for the U.S. Mint, and collectors were eager to grab the first-year issues. There are actually two distinct versions of the 1999-S Georgia quarter: the standard Copper-Nickel Clad version and the prestige 90% Silver version. Knowing which one you hold is the secret to unlocking its true market value.

Distinguishing Between Clad and Silver Georgia Proof Quarters
The most important factor in determining the value of your 1999-S Georgia quarter is its metal composition. The standard clad proof contains the same copper-nickel core as a regular quarter. However, the silver proof was struck on a blank consisting of 90% silver and 10% copper. To the naked eye, they look almost identical, but the silver version is significantly heavier and has a crisp, bright white edge rather than the sandwich-like copper stripe seen on the side of common quarters.
If you happen to have a silver version, you are looking at a much higher price point. While a clad proof might sell for the price of a cup of coffee, the 1999 Georgia quarter value in silver remains strong because of the intrinsic bullion value and collector demand. Many casual hunters use the CoinKnow platform to track these silver prices as the market fluctuates.

Professional grading also plays a massive role. A 1999-S Georgia quarter that is graded “Deep Cameo” (DCAM) by a service like PCGS or NGC will fetch a premium. A Deep Cameo coin has a stark contrast between the frosted design elements and the deep, reflective black fields of the coin’s background. These are the “beauty pageant winners” of the coin world and are the most sought-after by serious numismatists.
Analyzing the Current Market Value for Georgia Quarter Proofs
When you are ready to sell or trade your coin, it is vital to know that “Value” is subjective based on the coin’s condition. A coin that has been touched by oily fingers or scratched by other coins in a jar will lose its “Proof” premium quickly. Most collectors want these coins in their original mint packaging or inside a protective plastic slab.

The detailed 1999 Georgia quarter price guide indicates that even a small difference in grade—moving from a PR69 to a PR70—can result in a price jump of dozens or even hundreds of dollars. Because the 1999-S Georgia quarter was part of the inaugural year of the program, it carries a sense of nostalgia that later years sometimes lack.
| Coin Type & Grade | Estimated Market Value |
|---|---|
| 1999-S Clad Proof (PR65) | $3.00 – $5.00 |
| 1999-S Clad Proof (PR70 DCAM) | $25.00 – $40.00 |
| 1999-S 90% Silver Proof (PR65) | $12.00 – $18.00 |
| 1999-S 90% Silver Proof (PR70 DCAM) | $150.00 – $550.00 |
How Condition and Errors Affect Your Coin’s Worth
As with any collectible, the condition is the “make or break” factor. For the 1999-S Georgia quarter, “Eye Appeal” is the term experts use. If the coin has developed a iridescent rainbow-colored film over time, known as “toning,” it can actually increase the value to the right buyer. Conversely, if the coin has milky white spots (milk spits), the value might drop below the average market rate.

Beyond standard grades, some hunters look for errors. While errors are extremely rare on proof coins because of the strict quality control at the San Francisco Mint, they do happen. Double dies, where the letters or numbers appear doubled, or “struck through” errors, where a piece of dust was caught between the die and the coin, can turn a $5 coin into a $500 treasure. If you suspect your coin has a strange physical oddity, checking it against the high-resolution database on CoinKnow is a great first step before paying for professional authentication.
Remember that most Georgia quarters you find in your pocket are the Philadelphia (P) or Denver (D) strikes. These were made in the hundreds of millions and are generally only worth 25 cents unless they are in absolutely flawless, uncirculated condition. It is the “S” mint mark that tells you that you have something special. Always handle your proof coins by the edges to avoid leaving permanent fingerprints on the mirror-like surfaces.
Frequently Asked Questions
Q: How do I know if my 1999-S Georgia quarter is silver or clad?
A: The easiest way is to look at the edge of the coin. If you see a solid silvery-white color, it is likely the 90% silver version. If you see a copper-colored stripe, it is the standard clad version. Additionally, the silver version weighs 6.25 grams, while the clad version weighs 5.67 grams.
Q: Can I find a 1999-S Georgia quarter in my pocket change?
A: It is rare, but it happens! When people spend proof sets or inherited collections, these coins enter circulation. If they are found in change, they are usually “impaired proofs,” meaning they have scratches and wear, which significantly lowers their value to around $1-$2 for clad versions.

Q: What is the highest price ever paid for a 1999-S Georgia quarter?
A: Perfectly graded PR70 Deep Cameo silver versions have sold at major auctions for over $600. Prices vary based on the current demand for “Registry Set” coins among high-end collectors.
Q: Should I get my 1999-S Georgia quarter graded by PCGS?
A: You should only consider professional grading if the coin is in perfect condition and appears to be a Silver Proof. Since grading costs usually start around $30-$50 including shipping, it doesn’t make financial sense to grade a coin that is only worth $10.
