The 2007-S Washington Silver State Quarter is worth anywhere from $10 in standard proof condition to over $500 for perfect Deep Cameo specimens. While most of these coins are part of collectors’ sets, finding one in your possession could mean you are holding a significant premium over its face value.

Condition/Grade	Estimated Market Value
PR 65 (Typical Proof)	$10 – $15
PR 69 Deep Cameo	$25 – $40
PR 70 Deep Cameo (Perfect)	$150 – $550+

Understanding the 2007-S Silver State Quarter

The year 2007 was a busy time for the United States Mint as it continued the famous 50 State Quarters Program. During this year, five specific states were honored: Montana, Washington, Idaho, Wyoming, and Utah. While millions of these quarters were struck in copper-nickel for general circulation, the San Francisco Mint produced a limited number of “S” mint mark silver versions specifically for collectors.

If you have stumbled upon a 2007 quarter with an “S” mint mark, you first need to determine if it is the clad version or the silver version. The silver quarters are composed of 90% silver and 10% copper. These weren’t meant to buy a soda at a vending machine; they were sold in “Silver Proof Sets.” However, sets are often broken up, and sometimes these coins find their way into “the wild.”

Using a top coin identifier app can help you distinguish between the common clad version and the more valuable silver strike. If you are unsure what you have in your hand, check the edge of the coin. A silver quarter will have a solid silver-colored edge, whereas a clad quarter will show a distinct copper stripe. You can also use CoinKnow to get an instant identification and preliminary valuation based on current market trends.

Differentiating Between Clad and Silver Proofs

It is a common mistake for beginners to assume all “S” mint mark quarters are made of silver. In 2007, the San Francisco Mint produced both “clad” proofs (made of the same metal as pocket change) and “silver” proofs. The silver versions are significantly more desirable due to their precious metal content and lower mintage numbers.

The physical weight is the most reliable way to tell them apart without specialized equipment. A 2007-S clad quarter weighs 5.67 grams, while the 2007-S silver quarter weighs 6.25 grams. Because silver is denser than copper and nickel, the weight difference is a “smoking gun” for collectors.

Specification	Clad Proof Details	Silver Proof Details
Composition	Copper-Nickel Clad	90% Silver, 10% Copper
Weight	5.67 grams	6.25 grams
Mintage (Approx)	2.0 Million per state	1.3 Million per state

Grading and the “Deep Cameo” Factor

When discussing the 2007 silver quarter price, the term “Deep Cameo” (DCAM) is vital. Because these coins were struck using polished dies and specially prepared blanks, they feature a stunning contrast. The raised parts of the design (like Washington’s head) appear frosted and white, while the flat background (the field) looks like a deep black mirror.

Coin grading services like PCGS or NGC assign a numerical grade from 1 to 70. A grade of PR 69 means the coin is almost flawless to the naked eye. However, a PR 70—the perfect grade—is where the real money is. For the 2007-S Washington Silver Quarter, a PR 70 Deep Cameo can command a massive premium because collectors are willing to pay for perfection.

If you’re looking at your coin and it looks exceptionally shiny but has tiny scratches (known as “hairlines”), it has likely been handled or wiped with a cloth. Even small scratches can drop the value from $100 down to its melt value of about $5 or $6. Using CoinKnow‘s high-resolution photo analysis can help you spot these imperfections before you decide to send it off for professional grading.

Mintage Numbers for the 2007 Silver Quarters

The value of any coin is a direct result of supply and demand. In 2007, the mintage for silver quarters was relatively consistent across all five states. Unlike the early years of the 50 State Quarters program, by 2007, the Mint had perfected its production of silver proof sets, making these coins slightly more common than the 1999 issues, but still rare compared to billions of circulating quarters.

Identifying which specific state you have is the first step, as certain states (like Montana or Wyoming) may have slightly higher demand among regional collectors. However, generally, the 2007-S Silver series maintains a uniform price floor based on its 0.1808 troy ounces of pure silver.

2007 State Release	Silver Mintage (Approx)	Key Feature
Montana	1,313,481	Bison Skull
Washington	1,313,481	Salmon/Mount Rainier
Idaho	1,313,481	Peregrine Falcon
Wyoming	1,313,481	Bucking Horse
Utah	1,313,481	Golden Spike

Are 2007 Quarters Ever Found in Pocket Change?

The short answer is: yes, but it is rare. Most 2007-S silver quarters and even the clad “S” proofs were sold in protective plastic lenses. For one of these to end up in your pocket, someone had to break open a proof set and spend it as 25 cents. While it sounds crazy, it happens frequently during inheritances or when “non-collectors” accidentally spend a collection.

If you find a 2007-S silver quarter in circulation, it is known as “Proof in Circulation.” These coins will usually have scratches and have lost their “Deep Cameo” frostiness. In this state, the coin is worth its silver melt value plus a small premium. If it is the clad version (copper-nickel), it is usually worth about $0.50 to $1.00 because of the “S” mint mark curiosity.

Always check your change for the “S” mint mark. Even if the coin isn’t silver, an “S” mark from 2007 is always worth more than 25 cents to the right buyer. To stay updated on these niche values, many collectors rely on CoinKnow to track auction results and the fluctuating spot price of silver.

Key Errors to Look For in 2007 Quarters

While errors are much rarer in proof coins (because the Mint inspects them more closely), they aren’t impossible. In the 2007 series, collectors often look for “thicker” lettering or doubling. For example, some 2007-S silver proofs may show “doubled die” characteristics on the reverse side where the state design is featured.

Look closely at the word “Washington” or the date “1889” on the Washington state quarter. If you see a faint second image or a “shadow” next to the letters, you might have found an error. Errors on silver proofs are extremely valuable because they represent a failure in the Mint’s highest quality control tier.

Before you sell your coin, make sure to examine it under a 10x jeweler’s loupe. What looks like a scratch to the naked eye might actually be a valuable die crack. Many enthusiasts use digital tools to compare their finds with known error databases, ensuring they don’t accidentally spend a coin worth hundreds of dollars.

FAQ

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

A: The most effective method is the “Edge Test.” Hold the coin and look at the ribbed edge. If you see a solid silver/white color, it is likely the 90% silver version. If you see a orange/brown copper stripe, it is a clad proof worth significantly less. You can also do a “ping test” (carefully!), as silver has a higher-pitched, longer ring than copper-nickel.

Q: Is a 2007 Washington Quarter with no mint mark rare?

A: No. A 2007 quarter with no mint mark was minted in Philadelphia (“P” was often omitted or faint in older years, but by 2007, most have a “P”). If it has a “D”, it’s from Denver. These were minted in the hundreds of millions and are generally only worth 25 cents unless they are in absolutely superb, uncirculated condition.

Q: Why is the Washington state quarter special in the 2007 set?

A: It is frequently confused with the “Washington” on the head (obverse) of the coin. Every state quarter has George Washington on the front, but the 2007 Washington state quarter has the state name “Washington” and a salmon on the back. The silver proof version of this specific state is a favorite among Pacific Northwest collectors.

Q: What is the silver melt value of a 2007-S silver quarter?

A: A 90% silver quarter contains about 0.1808 troy ounces of pure silver. To find the current melt value, multiply 0.1808 by the current spot price of silver. Usually, this value stays between $4 and $6, which serves as the absolute “floor” price for the coin, regardless of its condition.
