The 2002-S Louisiana State Quarter is worth anywhere from $0.50 in typical proof condition to over $1,200 for rare silver high-grade specimens. While quarters you find in your pocket change are usually worth just face value, the “S” mint mark signifies a special coin produced exclusively for collectors.
| Coin Type | Grade/Condition | Estimated Value |
|---|---|---|
| 2002-S Louisiana Clad Proof | PR65 to PR69 | $0.50 – $5.00 |
| 2002-S Louisiana Silver Proof | PR69 DCAM | $10.00 – $15.00 |
| 2002-S Louisiana Silver Proof | PR70 DCAM (Top Pop) | $40.00 – $1,200+ |
Understanding the 2002-S Louisiana Quarter Mint Mark
If you have found a Louisiana quarter with a small “S” under the “In God We Trust” motto, you have a Proof coin. Unlike the Philadelphia (P) or Denver (D) quarters intended for general circulation, the San Francisco Mint produced the “S” versions specifically for coin sets sold to the public. To ensure you have accurately identified your find, using a top coin identifier app can help you distinguish between the two distinct versions of the “S” mint coin: the copper-nickel clad version and the 90% silver version.
Most Americans who find these in the wild are looking at “impaired proofs.” This means the coin was once in a protective plastic case but was spent as regular money. While these are technically rarer than the millions of P and D quarters, their market value depends heavily on their pristine finish. The 2002-S Louisiana quarter features a trumpet, a pelican (the state bird), and an outline of the Louisiana Purchase territory.
When searching through your collection, using the CoinKnow app can provide instant recognition of these details. The app helps users distinguish the mirror-like finish of a proof from the satin finish of a standard business strike. Even if the coin has scratches, knowing it is an “S” mint mark is the first step toward determining if you have a treasure or just twenty-five cents.

The Difference Between Clad and Silver 2002-S Quarters
The year 2002 saw the release of two different “S” mint Louisiana quarters. The first is the standard Clad Proof, made of the same copper-nickel composition as your every-day change. The second is the highly coveted Silver Proof. This version is made of 90% silver and 10% copper. Identifying the difference is crucial because the 2002 quarter value for silver versions is tied significantly to precious metal spots prices and collector demand.
You can check the edge of the coin to see if it is silver. If you see a solid silver-colored edge without a copper “sandwich” stripe, you likely have the silver version. Alternatively, a precision scale would show that the silver quarter weighs 5.25 grams, while the clad version weighs 5.67 grams. If you are unsure, the CoinKnow tool can guide you through these physical checks to ensure you don’t spend a silver coin by mistake.

Grading and Condition: Why PR70 is the Goal
In the world of proof coins, condition is everything. Coins are graded on a scale from 1 to 70. A 2002-S Louisiana quarter in “PR69” (Proof 69) is nearly perfect but might have a tiny microscopic flaw. These are very common. However, a “PR70” is a perfect coin with no visible flaws under 5x magnification. The difference in price is staggering. For example, looking at the market behavior for silver quarters of this era, a PR70 can sell for hundreds of dollars more than a PR69.
Collectors look for “Deep Cameo” (DCAM) or “Ultra Cameo” designations. This refers to the contrast between the frosted design elements (the pelican and trumpet) and the mirror-like background fields. A 2002-S Louisiana Silver quarter with a perfect 70 grade and Deep Cameo contrast represents the absolute pinnacle of this specific issue.

If you find a proof quarter in a “bank roll” or pocket change, it is almost certainly no longer a PR70. Once a coin is touched by human hands or clinks against other coins, it develops “hairlines” or tiny scratches. These “impaired proofs” generally sell for $1 to $2 to casual collectors who just want to fill a hole in an album.
Historical Context: The Louisiana Purchase Design
The 2002 Louisiana Quarter was the 18th coin released in the 50 State Quarters Program. It honors the 1803 Louisiana Purchase, which doubled the size of the United States. The design was chosen by the state’s citizens and finalized by the U.S. Mint’s engravers. It features the “Louisiana Purchase” map, which is a popular theme for history buffs and coin collectors alike.
Because Louisiana is the birthplace of Jazz, the trumpet and musical notes on the coin are particularly significant. This artistic appeal makes the 2002-S Louisiana quarter a favorite for “thematic” collectors who collect coins featuring music or birds. Understanding the history adds intrinsic value to the coin beyond just the metal or the grade.

When you use CoinKnow, you can often find the historical mintage figures for these coins. For the 2002-S Louisiana issue, the Mint produced roughly 3.1 million clad proofs and 892,529 silver proofs. While these numbers seem high, they are a tiny fraction of the hundreds of millions of quarters minted in Philadelphia and Denver that same year.
Errors to Look For on 2002 Quarters
While proof coins are struck with higher quality control, errors can still happen. Collectors search for “doubled dies,” where the letters or shapes on the coin appear to be doubled. On a 2002-S Louisiana quarter, you should look closely at the text “Louisiana” and “1812.”
Another common error to check for is the “S over S” or misplaced mint marks, though these are extremely rare in the modern proof era. If you find a coin that looks “off”—perhaps the metal looks different or there is a strange bump on the surface—it could be a mint error. High-quality photos processed through a coin app can often reveal these nuances that the naked eye misses.
| Potential Error | Description | Estimated Rarity |
|---|---|---|
| Doubled Die Obverse | Doubling on the words “Liberty” or “2002” | Very Rare |
| Die Polishing Lines | Fine scratches originating from the mint die | Common (Low Value) |
| Off-Center Strike | Design is not centered on the planchet | Extremely Rare for Proofs |
Where to Sell Your Louisiana State Quarter
If you discover that your 2002-S Quarter is a high-grade silver proof, you have several options for selling it. For coins worth $10 to $50, local coin shops or eBay are your best bets. For those rare PR70 Deep Cameo specimens that can fetch over $1,000, professional auction houses like Heritage Auctions or Stack’s Bowers are the preferred venues.

Before selling, ensure the coin is protected. Never clean your coins! Cleaning a proof coin will instantly destroy its collector value, as it leaves microscopic scratches that any professional grader will catch. Instead, place it in a PVC-free plastic flip or a coin capsule. This preserves the surface luster that drives the value for “S” mint quarters.
Most casual finds will be worth about $1.00 for the clad version if it’s in good shape. Many people choose to keep these coins in a family collection rather than selling them, as the “S” mint mark is a great conversation piece for teaching children about the US Mint and local history.
2002-S Louisiana Quarter FAQ
Q: Why do some 2002-S quarters have a different color?
A: The difference in color usually indicates the metal content. Clad quarters have a slightly brownish edge because of the copper core, while Silver Proof quarters are brilliantly white/silver all the way through. Over time, silver can also develop “toning,” a colorful oxidation that some collectors find beautiful.
Q: Can I find a 2002-S Louisiana Quarter in my change?
A: Yes, it is possible, but rare. These coins were never released into circulation by the government. When you find one in change, it means a collector (or someone who inherited a collection) spent a proof set coin as regular money. These are called “impaired proofs.”

Q: Is the 2002-S Silver Quarter real silver?
A: Yes, the silver proof version contains 90% pure silver. In 2002, the US Mint continued the tradition of offering silver versions of the state quarters for collectors who preferred precious metal over the standard copper-nickel.
Q: How much silver is in the Louisiana Silver Quarter?
A: Each silver quarter contains 0.1808 troy ounces of pure silver. This means even if the coin is scratched or damaged, it will always be worth at least its “melt value” based on the current price of silver on the global market.
Q: What is the most expensive 2002-S Louisiana Quarter ever sold?
A: High-grade silver examples in PR70 Deep Cameo condition have sold at major auctions for prices exceeding $1,200. Most sales, however, fall in the $10 to $35 range for high-quality silver proofs and $2 to $7 for clad proofs.
