The 2007-S Wyoming State Quarter is worth anywhere from $1.50 in typical Proof condition to over $45 for high-grade silver versions. While most people find regular quarters in their change, finding an “S” mint mark means you have a special coin produced specifically for collectors at the San Francisco Mint.

Understanding the 2007 S Wyoming Quarter Versions

When you look at a 2007 Wyoming quarter, the first thing you should do is check the mint mark located to the right of George Washington’s ponytail. If you see an “S,” you are holding a Proof coin. Unlike the millions of quarters made in Philadelphia (P) or Denver (D) for daily spending, these were sold in sets. You can easily determine your coin’s specifics using the top coin identifier app to see if you have the copper-nickel version or the more valuable silver edition.

There are actually two distinct types of “S” quarters from 2007. The first is the Clad Proof, which has the same metal composition as a standard quarter (copper-nickel). The second is the 90% Silver Proof. These look very similar to the naked eye, but the silver version is slightly heavier and has a bright white edge rather than a copper stripe. If you aren’t sure which one you have, the CoinKnow app can help you identify the metallic composition and current market demand instantly.

Current Market Value and Pricing Guide

The value of your 2007-S Wyoming quarter depends heavily on its “Grade” and its metal content. Because these coins were never intended for circulation, they usually remain in “Deep Cameo” condition—meaning the fields are mirror-like and the design elements look frosted. Collectors pay a premium for silver versions because of the intrinsic bullion value combined with the low mintage numbers.

To get an accurate idea of what your coin might sell for on the open market, refer to the current 2007 Wyoming quarter prices. Most clad proof versions will sell for a modest profit over face value, while silver versions fluctuate based on the spot price of silver. Below is a breakdown of the typical prices you can expect from coin dealers or online auctions.

Coin Type / Grade	Estimated Value
2007-S Wyoming Clad Proof (PR65)	$1.25 – $2.50
2007-S Wyoming Clad Proof (PR70)	$15.00 – $25.00
2007-S Wyoming Silver Proof (PR65)	$10.00 – $12.00
2007-S Wyoming Silver Proof (PR70)	$40.00 – $55.00

Identifying the Wyoming State Quarter Design

The Wyoming quarter was the 44th coin released in the 50 State Quarters Program. Its design is iconic, featuring the “Bucking Horse and Rider” silhouette, which has been a symbol of the state for over 100 years. This silhouette represents the rugged, independent spirit of the West. If you find one of these in your pocket change, it was likely broken out of a collector set by someone who didn’t realize its value.

When examining the reverse side, look for the date “1890,” which signifies the year Wyoming was admitted to the Union. If the coin looks exceptionally shiny—almost like a mirror—it is likely an “S” mint proof. For those building a full set, checking the 2007 state series price data can help you see how Wyoming compares to other states released that same year, such as Montana or Utah. High-grade specimens are increasingly sought after by registry set collectors who use CoinKnow to track their inventory.

Major Errors to Look For in 2007 Quarters

While the 2007-S Proof quarters are struck with high precision, the 2007 business strikes (P and D mints) are known for some interesting errors. Collectors often look for “Die Cracks” or “Grease Strikes” where parts of the design are missing. On Wyoming quarters specifically, look for the “Double Die” errors on the reverse, where the silhouette of the horse and rider might appear slightly blurred or doubled.

If you think you’ve found an error on a proof coin, be extra careful. Proof errors are extremely rare because the Mint inspects these coins individually. Before you spend money on professional grading, use the CoinKnow app to compare your coin’s features against known error catalogs. An authenticated error on a 2007 series quarter can turn a 25-cent coin into a hundred-dollar treasure for the right buyer.

FAQ about 2007-S Wyoming Quarters

Q: Is the 2007-S Wyoming quarter made of real silver?

A: It depends. The San Francisco Mint produced both a clad (copper-nickel) version and a 90% silver version. You can tell them apart by looking at the edge; if the edge is solid silver-colored with no copper stripe, it is likely the silver version.

Q: How many 2007-S Wyoming quarters were minted?

A: Approximately 2 million Clad Proofs and just over 1 million Silver Proofs were struck. This makes them significantly rarer than the P and D versions which had hundreds of millions produced.

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

A: It is rare but possible. These are “Proof” coins meant for collectors. If you find one in circulation, it is called an “impaired proof.” It will likely have scratches and lose much of its premium value, but it is still a cool find!

Q: What is the most valuable 2007 Wyoming quarter?

A: The most valuable version is usually a 2007-S Silver Proof graded PR70 (Perfect condition) by a service like PCGS or NGC, which can sell for over $50. Rare mint errors on P or D coins can also fetch high prices.
