The 2007-S Washington State Quarter is worth anywhere from $1.50 in typical Proof condition to over $1,000 for high-grade Silver Proof specimens. While most quarters you find in your pocket change today are only worth twenty-five cents, those bearing the “S” mint mark from San Francisco were struck specifically for collectors and hold a premium over face value.
| Condition / Variety | Estimated Value |
|---|---|
| 2007-S Clad Proof (PR69) | $2.00 – $5.00 |
| 2007-S Clad Proof (PR70) | $25.00 – $45.00 |
| 2007-S Silver Proof (PR69) | $12.00 – $18.00 |
| 2007-S Silver Proof (PR70) | $50.00 – $120.00 |
History and Background of the Washington State Quarter
The 2007 Washington Quarter represents the 42nd release in the groundbreaking 50 State Quarters Program, which ran from 1999 to 2008. This specific coin honors the state of Washington, often called the “Evergreen State.” The design features a majestic king salmon breaching the water in front of Mount Rainier, a symbol of the Pacific Northwest’s natural beauty.
If you have stumbled upon a shiny version of this coin in a collection, you might be wondering about its true auction price. Using a top coin identifier app can help you distinguish between the common copper-nickel versions and the more valuable versions intended for collectors. Remember that while billions of quarters were minted for circulation in Philadelphia (P) and Denver (D), the San Francisco (S) mint produced a much smaller number of “Proof” coins.
For everyday Americans, identifying the 2007-S Washington State Quarter is the first step toward finding a hidden treasure. These coins were never meant to be spent in grocery stores or vending machines; they were originally sold in protective plastic sets by the U.S. Mint. However, over the years, many of these sets have been “broken up,” and individual coins sometimes find their way into general circulation. When they do, they are easy to spot because of their mirror-like finish and crisp details.

Understanding the 2007-S Mint Mark and Proof Quality
The “S” mint mark is the hallmark of the San Francisco Mint. Unlike the P and D quarters you see daily, the 2007-S was struck using special polished dies and planchets (coin blanks). The term “Proof” refers to the method of manufacture, not necessarily the condition, though most Proofs are in pristine shape. In the world of numismatics, the 2007-S Washington quarter worth is heavily dependent on whether the coin is a standard “clad” version or a 90% silver version.
The San Francisco Mint produced two distinct types of quarters in 2007. The Clad Proof is made of the same copper-nickel composition as standard quarters. The Silver Proof is made of 90% silver and 10% copper. To the naked eye, they look similar, but the silver version is heavier and has a brilliant white edge rather than the brown copper stripe seen on the side of a clad coin.

If you are unsure which one you have, the CoinKnow app can be a lifesaver. By taking a simple photo, CoinKnow uses advanced image recognition to help you determine the composition and surface quality of your coin. A 2007-S Silver Proof will always command a higher price than its clad counterpart simply because of its precious metal content and lower mintage numbers.
Detailed Price Guide for 2007-S Clad Proof Quarters
Clad Proofs are the most common type of “S” mint quarters found by hobbyists. In 2007, the mint produced several million of these to satisfy the demand of collectors who bought the annual Proof Sets. Because so many were kept in protective cases, finding one in “Perfect” condition (graded PR70) is the goal for serious investors.
| Grade | Price (Clad) | Rarity Factor |
|---|---|---|
| PR65 (Typical) | $1.50 – $2.25 | Very Common |
| PR68 (Near Perfect) | $3.00 – $7.00 | Common |
| PR69 (Deep Cameo) | $8.00 – $15.00 | Available |
| PR70 (Flawless) | $30.00 – $55.00 | Scarce |
Most clad 2007-S quarters that have been circulated (removed from their original packaging and spent) will only be worth $0.50 to $1.00 because they likely sustained scratches. However, if you find one that still looks like a mirror, keep it! Even a small premium is better than face value.

The demand for these coins often fluctuates based on the interest in “registry sets,” where collectors compete to own the highest-graded example of every state quarter. A PR70 specimen, which shows no visible flaws even under 5x magnification, is the ultimate “Holy Grail” for a 2007-S Washington Clad enthusiast.
Value of the 2007-S Silver Proof Washington Quarter
The Silver Proof 2007-S Washington State Quarter is a favorite among stackers (who collect silver) and numismatists alike. Because it contains 0.1808 troy ounces of pure silver, its value will never drop below the spot price of silver. When silver prices rise, the value of this coin rises automatically.
| Grade | Price (Silver) | Silver Content (oz) |
|---|---|---|
| Raw / Ungraded | $8.00 – $12.00 | 0.18084 |
| PR69 Deep Cameo | $15.00 – $25.00 | 0.18084 |
| PR70 Deep Cameo | $65.00 – $150.00+ | 0.18084 |
For the average American, telling the difference between clad and silver can be tricky. A quick “tissue test” (laying a single ply of tissue over the coin) or checking the edge for a solid silver color can help. However, for a definitive answer, using a professional tool like CoinKnow can provide instant feedback on what to look for, saving you a trip to a coin shop.

Collectors specifically look for the “Deep Cameo” (DCAM) effect on these silver quarters. This is when the raised parts of the design (like the salmon and Mount Rainier) look frosted and white, while the flat fields look like a deep, black mirror. The higher the contrast, the more valuable the coin becomes.
Identifying Errors on 2007 Washington Quarters
While errors are much rarer on Proof coins like the 2007-S compared to regular circulation coins, they do exist. Errors can drastically increase the value of a Washington State Quarter. Some common errors found in the series include “Die Chips,” where a small piece of the steel die breaks off, leaving an extra bump of metal on the coin’s surface.
Another popular error category for State Quarters is the “Double Die.” If the die was struck twice during its own creation, the resulting quarters will show doubling in the lettering or the design. While no major “mega-errors” have been widely reported for the 2007-S Washington specifically, subtle doubling can still fetch a premium from specialists.
Because Proof coins undergo a rigorous inspection at the mint, errors that slip through are often worth hundreds of dollars. If you see something “funky” on your coin—like a letter that looks like it has a shadow or a weird blob of metal—it is worth having it appraised. Specialized apps or online communities can help you verify if your “mistake” coin is a genuine Mint error or just post-mint damage.

How to Store and Protect Your 2007-S Quarter Value
If you discover you have a 2007-S Washington quarter worth a significant amount, your first priority should be preservation. Proof coins are extremely sensitive to oils from human skin. If you touch the mirror-like surface with your bare thumb, the oils will eventually leave a permanent “fingerprint” stain that can reduce the grade from a PR70 down to a PR60, costing you dozens of dollars in value.
Always handle collector coins by their edges or use lint-free cotton gloves. For long-term storage, avoid the cheap “PVC” plastic flips, as these can cause “PVC damage,” a green, gooey residue that eats into the metal. Instead, use PVC-free plastic holders or specialized “slabs” if you decide to have the coin professionally graded by services like PCGS or NGC.
Maintaining the condition is the only way to ensure the value of your Washington State Quarter continues to grow. Many collectors use the CoinKnow app to catalog their findings and track the market value of their collection over time. It’s a great way to stay organized and know exactly what your “treasure chest” is worth at any given moment.
FAQ: Common Questions About the 2007-S Washington Quarter
FAQ
Q: Can I find a 2007-S Washington Quarter in my pocket change?
A: It is possible, but rare. These coins were issued in collector sets. If you find one in circulation, it is likely an “impaired proof,” meaning someone broke it out of a set and spent it. It will still have the “S” mint mark but will likely have scratches and wear.

Q: How can I tell if my 2007-S Quarter is Silver or Clad?
A: Look at the edge of the coin. If you see a copper or brown stripe, it is a Clad (copper-nickel) version. If the edge is solid silver/white, it is a Silver Proof. You can also weigh the coin: a clad quarter weighs 5.67 grams, while a silver quarter weighs 6.25 grams.
Q: Is the 2007 Washington Quarter from Philadelphia or Denver worth anything?
A: Most P and D mint quarters from 2007 are only worth their face value of $0.25 if they have been used in circulation. However, if they are in “Uncirculated” condition (Mint State), they might be worth $1.00 to $5.00 to a collector building a set.
Q: What is a “Satin Finish” 2007 Washington Quarter?
A: In 2007, the U.S. Mint also produced “Satin Finish” coins for Uncirculated Mint Sets. These were minted in Philadelphia and Denver, not San Francisco. They have a smooth, matte appearance rather than a mirror-like Proof finish and are a separate category for collectors.
