The 2007-S Washington Silver States Quarter Dollar is worth anywhere from $5 to $15 in typical proof condition, but high-grade examples graded PR70 by PCGS or NGC can sell for $30 to $75 or more. If you’ve come across one of these silver quarters in a collection or old box, you might be sitting on a small treasure worth knowing about.
What Is the 2007-S Washington Silver States Quarter?
The 2007-S Washington Silver States Quarter is a special proof coin struck at the San Francisco Mint specifically for collectors. It was not made for everyday circulation — you won’t find these in your pocket change. These quarters are part of the long-running 50 State Quarters Program, which ran from 1999 to 2008, and the 2007 series honored four states: Montana, Washington, Idaho, and Wyoming, plus Utah.
The “S” mintmark stands for San Francisco, and the silver version contains 90% silver and 10% copper, just like pre-1965 U.S. coins. That silver content gives it real intrinsic value beyond just its collector appeal. If you’re not sure whether your coin is silver or clad, a coin identification app can help you tell the difference quickly and accurately. CoinKnow is a great option that lets you photograph the coin and get instant details about its metal composition and mint origin.
How Much Is the 2007-S Silver Quarter Worth Today?
The value of a 2007-S Washington Silver States Quarter depends on a few key factors: which state design it carries, its grade, and whether it has been certified by a professional grading service. Here’s a general look at what these coins sell for across different grades:
| Coin Description | Grade | Estimated Value |
|---|---|---|
| 2007-S Silver Quarter (any state) | PR65 | $5 – $8 |
| 2007-S Silver Quarter (any state) | PR68 | $10 – $18 |
| 2007-S Silver Quarter (any state) | PR69 | $15 – $30 |
| 2007-S Silver Quarter (any state) | PR70 (Perfect) | $40 – $75+ |
| Full Silver Proof Set (5 coins) | PR69 Set | $40 – $80 |
Silver melt value also plays a role. With each coin containing roughly 0.1808 troy ounces of silver, at $28 per troy ounce (a typical recent price), the melt value alone is about $5.06 per coin. That creates a natural price floor even for lower-grade examples. For the most current pricing, you can check detailed 2007 quarter value data including silver proof varieties to see real market comparisons.
What Makes Some 2007-S Silver Quarters More Valuable?
Not all 2007-S Silver State Quarters are equal in value. The single biggest factor is coin grade — and specifically whether the coin has been graded and slabbed by PCGS or NGC. A PR70 Deep Cameo coin has mirror-like fields and frosted devices with absolutely no imperfections under magnification. These are the coins that command top dollar at auction.
The “Deep Cameo” or “DCAM” designation also adds value. This refers to the high contrast between the reflective background and the frosted raised design. Most 2007-S proof quarters come with at least a Cameo finish, but Deep Cameo examples are the most desirable to serious collectors.
Packaging matters too. If your coin is still in its original U.S. Mint proof set box with the certificate of authenticity, it’s more appealing to buyers. Loose coins without packaging still sell, but often at slightly lower prices unless they’ve been graded independently. CoinKnow can help you understand what condition your coin might be in and what features to look for before you decide whether professional grading makes financial sense.
Should You Get Your 2007-S Silver Quarter Graded?
Grading costs money — typically $25 to $50 or more per coin through PCGS or NGC — so it only makes financial sense if your coin could be a PR69 or PR70. For average examples, the grading fee might exceed the value gained.
That said, if you have a complete 2007-S Silver Proof Set in pristine condition, submitting the full set for grading could unlock significantly more value. PR70 sets in original government packaging regularly sell for double or triple what raw sets fetch.
Before spending money on grading, use CoinKnow to take a close look at your coin and compare it to graded examples. It’s a smart first step that can save you time and money, and it helps you make a more informed decision about whether professional certification is worth pursuing.

Frequently Asked Questions
Q: How do I know if my 2007-S quarter is silver or clad?
A: Look for the “S” mintmark on the obverse (heads side) under “IN GOD WE TRUST.” Silver proof quarters also have a slightly different luster than clad versions. You can weigh the coin — silver quarters weigh about 6.25 grams versus 5.67 grams for clad. A coin identification app can also help confirm this.
Q: Which 2007-S state quarter design is the most valuable?
A: In most cases, all five 2007-S Silver State Quarter designs have similar values since mintage numbers are comparable. However, error coins or coins with unusual die characteristics can command premiums. Montana and Wyoming designs have attracted slightly higher collector interest in certain grades.
Q: Where is the best place to sell a 2007-S Silver States Quarter?
A: eBay is one of the most active marketplaces for these coins, especially for raw (ungraded) examples. Coin shows, local dealers, and Heritage Auctions are good options for certified high-grade coins. Always compare recent sold listings before pricing your coin to ensure you’re getting fair market value.
