What Is the 2007-S Montana State Quarter?
The 2007-S Montana State Quarter was issued by the United States Mint as part of the long-running 50 State Quarters Program, which ran from 1999 to 2008. The “S” mint mark stands for the San Francisco Mint, which produced proof versions of these coins specifically for collector sets — not for everyday circulation.

The obverse features the classic George Washington portrait, while the reverse showcases Montana’s stunning landscape: a bison skull set against the backdrop of the Rocky Mountains and the state motto “Big Sky Country.”
Because San Francisco proof quarters were never meant to circulate, most examples you’ll find are in excellent condition. They were sold in annual proof sets, which means they were carefully handled and stored from day one. That matters a lot when determining value.

2007-S Montana Quarter Value by Grade
The value of a 2007-S Montana Quarter depends heavily on its grade and whether it’s a standard proof or a Silver Proof version. The San Francisco Mint produced both a clad (copper-nickel) proof and a 90% silver proof — the silver version is worth significantly more.
Here’s a quick breakdown of typical market values:

Silver vs. Clad: Why It Makes a Difference
One of the most important things to know about the 2007-S Montana Quarter is whether yours is silver or clad. Both were made at the San Francisco Mint, but the silver proof was sold as part of a premium Silver Proof Set and contains 90% silver content.

A quick way to tell the difference: weigh your coin. A clad quarter weighs about 5.67 grams, while the silver version comes in at approximately 6.25 grams. You can also look at the coin’s edge — a silver quarter won’t show the copper-colored stripe you’d see on a clad coin.
Silver proof quarters are worth more for two reasons: the metal content itself adds intrinsic value, and they tend to have sharper cameo contrast, making them more attractive to collectors. If you’re unsure which version you have, CoinKnow can help you identify and verify the type quickly using your phone’s camera.

Errors and Varieties That Could Be Worth More

Like many coins in the State Quarters series, the 2007-S Montana Quarter may have minor die varieties or striking anomalies that attract premium prices among error coin collectors. While major errors are rare for proof coins — since they go through more quality control — doubled die varieties and unusual cameo contrast have been documented on some examples.
If you suspect your coin has an error, it’s worth getting it professionally graded by PCGS or NGC. Certified PR70 DCAM examples (the highest possible grade) routinely sell for multiples of their ungraded counterparts.
For a broader look at what 2007 State Quarters are worth across different mint marks and conditions, exploring a comprehensive coin value resource can save you a lot of guesswork.
