The 2003-S Maine State Quarter is worth anywhere from $1.50 in standard clad proof condition to over $50 for high-grade silver versions. While most Maine quarters found in your pocket change are only worth their face value of 25 cents, those bearing the “S” mint mark were specially struck for collectors and enthusiasts.
| Coin Version | Average Value (PR65) | Top Grade Value (PR70) |
|---|---|---|
| 2003-S Clad Proof | $1.50 – $4.00 | $15 – $25 |
| 2003-S Silver Proof | $10.00 – $15.00 | $45 – $60+ |
Understanding the History of the 2003 Maine Quarter
The Maine State Quarter was the 23rd coin released in the United States Mint’s ambitious 50 State Quarters Program. Issued in 2003, this coin celebrates the “Pine Tree State” with a design featuring the Pemaquid Point Lighthouse and a schooner at sea. For many everyday Americans, finding one of these in a jar of coins is a reminder of a beautiful coastal heritage.
If you are trying to determine if your find is a rarity or just a common circulation coin, using the top coin identifier and value app can save you hours of research. Most Maine quarters were minted in Philadelphia (P) or Denver (D) for general use. However, the 2003-S versions were produced exclusively at the San Francisco Mint.
The CoinKnow app is particularly helpful here, as it can help you distinguish between a shiny circulated coin and a true proof strike. Proof coins are made using polished dies and planchets, resulting in a mirror-like finish that stands out immediately. If you see an “S” under the “In God We Trust” motto, you have found a collector’s item that was never intended to spend at a grocery store.

Identifying the 2003-S Clad vs. Silver Maine Quarter
When looking at 2003-S Maine State Quarter values, the first thing you must do is determine the metal composition. The San Francisco Mint produced two distinct versions of the proof quarter in 2003: the standard copper-nickel clad version and a special 90% silver version.
To tell them apart, check the “edge” of the coin. If you see a solid silver-colored stripe, it is likely the silver version. If you see a copper or orange stripe through the middle, it is the clad version. The silver version is significantly heavier and carries a much higher premium due to its precious metal content.

For those tracking the market, checking the latest current Maine quarter auction results is the best way to see what buyers are actually paying. Investors often prefer the silver 2003-S Maine quarter because it hedges against inflation while remaining a legitimate piece of numismatic history.
| Feature | Clad Proof (S) | Silver Proof (S) |
|---|---|---|
| Composition | 91.67% Copper, 8.33% Nickel | 90% Silver, 10% Copper |
| Weight | 5.67 grams | 6.25 grams |
| Edge Appearance | Copper streak visible | Solid silver/white |
Why Condition and Grading Matter for Value
In the world of coin collecting, condition is everything. A “Proof” coin is already expected to be in excellent condition, but professional graders like PCGS or NGC use a 70-point scale. A 2003-S Maine Quarter graded as PR69 (nearly perfect) is common, but a PR70 (perfect) can command a significant premium.

Many people find these coins in “Proof Sets” that have been opened. If the coin has been handled without gloves, skin oils can cause “milking” or cloudiness on the surface, which drops the value instantly. If you are unsure about the state of your coin, the CoinKnow tool can provide a visual comparison to help you estimate its grade.
Detailed Maine quarter price guide data shows that even a small scratch invisible to the naked eye can turn a $50 coin into a $5 coin. Always handle your quarters by the edges to preserve their value and avoid “hazing” on the delicate mirrored surfaces.
Mint Errors to Look For in 2003 Quarters
While the 2003-S Maine State Quarter is known for its high production quality, error hunters still keep a keen eye out. Because proof coins are struck twice with high pressure, errors are exceptionally rare and highly sought after. Typical errors for the 50 State Quarters series include doubled dies, off-center strikes, or “capped dies.”

If you find a Maine quarter that looks “blurred” or has letters that appear doubled, you might have a valuable rarity. Even the Philadelphia and Denver business strikes can have errors that make them worth more than the standard 2003-S proof versions. For example, a “Die Break” or “Cud” on the lighthouse design could attract significant interest from error specialists.
Using CoinKnow, you can zoom in on high-quality images of known errors to see if your coin matches any documented varieties. While most 2003 quarters are standard, the excitement of finding a one-of-a-kind error is what keeps the hobby of “pocket change hunting” alive for so many Americans.
| Mint Mark | Mintage Type | Rarity Level |
|---|---|---|
| P (Philadelphia) | Circulation | Common |
| D (Denver) | Circulation | Common |
| S (San Francisco) | Proof Only | Collector Item |
How to Sell Your 2003-S Maine Quarter
If you’ve identified your coin as a 2003-S Maine Quarter and want to turn it into cash, you have several options. For standard clad proof coins, your best bet is often a local coin shop or a bulk listing on eBay. Because their value is relatively low (under $5), selling them individually can sometimes cost more in shipping and fees than the coin is worth.

However, if you have a Silver Proof version or a coin you believe would grade at PR70, professional auction houses or specialized coin forums are better avenues. Coin collectors often look for the “Deep Cameo” (DCAM) designation, where the frosted design contrasts sharply against the mirror fields.
Before selling, always get a second opinion. A quick scan with a mobile app or a visit to a local numismatic club can ensure you don’t accidentally sell a $50 silver coin for the price of a $2 clad coin. Knowing the specific nuances of your coin’s grade and composition is the key to getting the best price possible.
Frequently Asked Questions About 2003 Maine Quarters
Q: Is a 2003 Maine quarter with no mint mark rare?
A: No. Quarters with no mint mark were struck in Philadelphia (the “P” was sometimes omitted or very faint on older coins, but usually, 2003 coins have a visible P). These were minted in the hundreds of millions and are typically only worth 25 cents unless they are in perfect, uncirculated condition.
Q: How much silver is in a 2003-S Silver Maine Quarter?
A: These coins contain 0.1808 troy ounces of pure silver. This means their “melt value” fluctuates with the spot price of silver. Even if the coin is damaged, it will always be worth at least the value of its silver weight, which is usually much higher than 25 cents.

Q: I found an “S” mint mark quarter in my pocket change. Is it a proof?
A: Highly likely! Sometimes collectors break open proof sets and spend the coins. While it is technically a “proof,” being in circulation causes scratches and wear, which significantly reduces the collector value. It is still a cool find and worth keeping, even if it’s no longer in “Gem” condition.
Q: What is the most expensive Maine Quarter ever sold?
A: Highly graded Silver Proofs (PR70 Deep Cameo) have sold for over $100 at various auctions. However, most collectors can expect to pay between $10 and $20 for a high-quality silver specimen for their folders.
Q: Does the Maine State Quarter have any famous errors?
A: There are no major “named” errors like the Wisconsin “Extra Leaf” quarter for Maine. However, generic errors like off-center strikes are always possible. Use a magnifying glass to check for any irregularities in the lighthouse or the schooner’s sails.
