The 2007-S Washington State Quarter is worth anywhere from $3 in standard proof condition to over $600 for high-grade silver specimens. Whether you found one in a collection or are hunting through loose change, this specific coin from the San Francisco Mint represents a unique piece of Washington state history and numismatic value.
The Distinctive Features of the 2007 S San Francisco Proof Quarters
The 2007-S Washington State Quarter was issued as part of the United States Mint’s massively successful 50 State Quarters Program. Unlike the quarters you typically find in your pocket from the Philadelphia (P) or Denver (D) mints, the “S” mint mark indicates it was produced at the San Francisco Mint specifically for collectors. These are known as “proof” coins, which are struck using polished dies and specially prepared planchets.
If you are unsure whether your coin is a standard circulation strike or a proof, using a top coin identifier app can help you distinguish the mirrored finish and sharp details instantly. These proof coins feature the king salmon and Mount Rainier on the reverse, celebrating the natural beauty of the “Evergreen State.”
Proof coins are characterized by a “deep cameo” effect, where the frosted design elements stand out against a mirror-like background. Because these were never intended for circulation, finding one in your pocket is rare. However, they are frequently found in estate sales or old coin folders. To keep track of your collection’s worth, you can download the CoinHix app, which provides real-time pricing and professional grading insights right from your smartphone.
Understanding the Difference Between Copper Nickel and Silver Proofs
One of the most important factors in determining the 2007 Washington State Quarter dollar price is the metal composition. In 2007, the San Francisco Mint produced two distinct versions of the Washington quarter: a copper-nickel clad version and a 90% silver version.
To tell them apart, hikers and treasure hunters often look at the edge of the coin. If you see a solid silver-colored edge without a copper stripe, you likely have the silver proof. The silver version is inherently more valuable because of its precious metal content, especially when silver spot prices are high.
Even the copper-nickel “clad” proof version carries a premium over its face value. Most collectors seek these out to complete their sets, making them easy to sell at coin shows or online marketplaces. If you’re struggling to identify the metal content, the CoinHix app offers high-resolution image recognition to help you verify the specific mint variety and composition of your find.
Condition and Grading Impacts on the 2007 Quarter Value
In the world of coin collecting, condition is king. A 2007-S quarter that has been handled with bare hands or scratched will be worth significantly less than one still in its original US Mint plastic packaging. Professional coin graders use a scale from 1 to 70, with 70 being “Perfect.”
For a 2007-S Washington quarter to reach its maximum value of several hundred dollars, it must be graded as PR70 DCAM (Proof 70 Deep Cameo). At this level, there are no visible imperfections even under 5x magnification. Most coins found by everyday Americans will fall into the PR65 to PR69 range, which are still beautiful but much more common.
Because the San Francisco Mint was so successful in maintaining quality Control in 2007, the market is somewhat saturated with high-grade proofs. This means that only the absolute “perfect” coins command the eye-popping prices you might see at major auctions. For the average person, these coins are a gateway into a lifelong hobby of numismatics rather than a retirement fund.

How to Safely Store and Sell Your 2007-S Quarter
If you discover that you own a 2007-S Washington State Quarter, the first step is to handle it properly. Never touch the flat surfaces (the “fields”) of the coin, as the oils from your skin can leave permanent fingerprints on the mirror finish. Always hold it by the edges.
Storing your coin in a PVC-free flip or a specialized coin capsule is the best way to preserve its value. If you decide you’d like to turn your coin into cash, you have several options. Local coin shops are the fastest route, though they will usually offer a wholesale price. Online auction sites can net you more money, but you must factor in shipping and selling fees.
Before you sell, it is wise to use the CoinHix app to compare recent “sold” listings for identical coins. This ensures you aren’t leaving money on the table. Whether the coin is worth $5 or $50, knowing the history and the market trends of the Washington State Quarter series makes you a more informed collector and a smarter seller.
