The 2007-S Washington State Quarter is worth anywhere from $1.50 in typical proof condition to over $100 for high-grade silver versions. While these coins were not released into general circulation, many Americans find them in inherited collections or “proof sets” and wonder about their actual market price today.

Coin Type	Mintage	Common Grade Value	Top Grade (PF70) Value
2007-S Clad Proof	~2.5 Million	$1.50 – $4.00	$15 – $25
2007-S Silver Proof	~1.3 Million	$8.00 – $12.00	$45 – $110

Identifying Your 2007-S Washington State Quarter

The 2007-S Washington State Quarter is a unique entry in the 50 State Quarters Program, representing the state of Washington (“The Evergreen State”). To start, you need to verify if your coin is actually the “S” mint mark version. If you are unsure exactly what you have in your hand, using a top coin identifier app can help you distinguish between the common Philadelphia/Denver issues and the San Francisco proofs.

Unlike the coins you find in your pocket change, the “S” mint mark quarters were struck at the San Francisco Mint specifically for collectors. These coins feature a “Proof” finish, characterized by mirror-like backgrounds and frosted foreground details. The 2007 Washington design features a leaping salmon against a backdrop of Mount Rainier, a truly iconic image of the Pacific Northwest.

Because these were sold in protective plastic cases by the U.S. Mint, they are usually found in excellent condition. However, if they have been removed from their cases and handled, their value can drop significantly due to fingerprints or scratches. Professional collectors often use tools like CoinKnow to track the market fluctuations of these proof sets, ensuring they don’t overpay for raw coins.

The Difference Between Clad and Silver 2007-S Quarters

One of the most important factors in determining the 2007-S Washington state quarter price is the metal composition. In 2007, the San Francisco Mint produced two distinct versions of the Washington state quarter. The first is the “Clad” version, which is made of the same copper-nickel composition as standard quarters.

The second, and more valuable version, is the 90% Silver Proof. These were sold in special “Silver Proof Sets.” To the untrained eye, they look very similar, but the silver version is heavier and has a distinct “ping” when dropped. More importantly, if you look at the edge of the coin, a silver proof will be solid silver-colored, while a clad proof will show a copper stripe along the rim.

Knowing which one you have is the difference between a coin worth a few dollars and one worth ten dollars or more just in scrap metal value. Serious hobbyists use CoinKnow to keep a digital inventory of these variations, as the silver market changes daily, directly impacting the value of the 2007-S Silver Washington Quarter.

Composition	Weight	Edge Appearance	Intrinsic Value
Copper-Nickel Clad	5.67 grams	Copper/Red Stripe visible	$0.25
90% Silver	6.25 grams	Solid White/Silver	Variable (Silver Spot)

Grading and Condition Standards for 2007-S Coins

When it comes to the 2007-S Washington state quarter value, condition is everything. Since these coins were never meant to be spent in a grocery store, almost all of them are technically “Uncirculated.” In the world of coin grading, proofs are graded on a scale from PR1 to PR70.

A PR70 (Proof 70) is considered a “perfect” coin under 5x magnification. For the 2007-S Washington State Quarter, a PR70 Deep Cameo (DCAM) can fetch a significant premium. These coins have intense contrast between the shiny fields and the white, snowy frost on the salmon and the mountain. Even a tiny hairline scratch caused by a piece of cloth can downgrade a coin to PR69, cutting its value by more than half.

If you find a 2007-S quarter that looks a bit dull or has light scratches, it likely spent some time in circulation or was handled poorly. These “impared proofs” are generally only worth their face value ($0.25) if clad, or their weight in silver if they are the 90% version. Always handle your coins by the edges to preserve their grade and future resale potential.

Market Trends for the 50 State Quarters Series

The 50 State Quarters Program was immensely popular, but because the U.S. Mint produced them in such high volumes, most are not “rare” in the traditional sense. However, as the 20th anniversary of the program has passed, we are seeing a resurgence in interest. Collectors who grew up filling maps with these quarters are now looking for high-end proof versions to complete professional sets.

The 2007-S Washington State Quarter is part of the later years of the program, which generally saw slightly lower mintage numbers for proof sets compared to the early years like 1999. This makes the 2007 issues slightly more desirable than their predecessors. When selling, you will find that “Silver” continues to be the primary driver of value.

If you are looking to sell, it is best to check recent auction results on platforms like eBay or use a dedicated app like CoinKnow. Prices can jump if a specific state becomes “hot” or if the price of silver bullion spikes. Keeping an eye on these trends ensures you don’t sell a valuable silver proof at a “clad” price.

State Quarter Year	Proof Set Demand	Rarity Level
1999-S	Very High	Low/Moderate
2007-S (Washington)	Moderate	Modern Common
2009-S (Territories)	High	Moderate

Potential Errors to Look For in 2007 Quarters

While errors are much rarer in proof coins because the Mint exercises higher quality control, they are not impossible. For a 2007-S Washington State Quarter, an error could skyrocket the value into the hundreds or even thousands of dollars. One type of error to look for is a “Double Die,” where the letters or numbers appear doubled.

Another rare occurrence is a “Struck Through” error, where a piece of debris or grease gets between the die and the coin blank, leaving an indentation or a blurry area on the design. Because proof dies are cleaned frequently, these are the “holy grails” for state quarter collectors.

Always inspect the rim and the fields of the coin under a magnifying glass. If you see something that looks “wrong” or different from other 2007 quarters, you might have a rare mint error. Even a minor error on a proof coin is highly collectible because of how strict the San Francisco Mint is during the production of these special sets.

FAQ

2007-S Washington State Quarter Common Questions

Q: Can I find a 2007-S Washington Quarter in my pocket change?

A: It is very rare, but possible. These were only sold in sets to collectors, but sometimes people break open the sets and spend the coins. If you find one with an “S” mint mark in circulation, it is called an “impaired proof” and is usually worth about 25 cents to $1.

Q: How can I tell if my 2007-S Quarter is silver without a scale?

A: The easiest way is the “Tissue Test” or the “Edge Test.” Look at the edge of the coin; if you see a solid silver/white color with no copper stripe, it is likely silver. Also, if you lay a single ply of white tissue over a clad coin, it looks grey; over a silver coin, it looks white.

Q: Is the 2007-S Washington Quarter a good investment?

A: While they aren’t going to make you a millionaire, silver proofs are a stable way to hold silver bullion with a historical premium. Most collectors buy them for the beauty of the design rather than as a primary financial investment.

Q: What is the most expensive 2007-S Washington Quarter ever sold?

A: Top-tier PR70 Deep Cameo Silver Proofs have sold for over $150 at major auctions when the market is competitive. However, most collectors should expect a value between $10 and $30 for high-quality specimens.
