The 2010-S Yellowstone Quarter is worth anywhere from $1 to $5 for a standard proof coin, but premium deep cameo examples in perfect condition can fetch $10 to $25 or more. If you’ve got one sitting in a drawer or stumbled across it in an old coin collection, you’re in the right place to find out exactly what it’s worth.
What Is the 2010-S Yellowstone Quarter?
The 2010-S Yellowstone Quarter is part of the America the Beautiful Quarters program, launched by the U.S. Mint in 2010 to honor national parks and historic sites across the country. Yellowstone National Park in Wyoming was one of the first five parks featured in the series, making it one of the most iconic issues in the entire program.
The “S” mint mark tells you this coin was struck at the San Francisco Mint, which is known for producing proof coins — coins made with specially polished dies and blanks for collectors rather than general circulation. These coins were never meant to jingle in your pocket. They were made to sit in display cases and coin folders.

How Much Is the 2010-S Yellowstone Quarter Worth Today
The value of the 2010-S Yellowstone Quarter depends on a few key factors: the coin’s grade, whether it’s a standard proof or a silver proof, and whether it’s been certified by a grading service like PCGS or NGC.
Here’s a general value breakdown:
| Coin Type | Grade | Estimated Value |
|---|---|---|
| Clad Proof | PR65 | $1 – $3 |
| Clad Proof Deep Cameo | PR69 DCAM | $5 – $10 |

Silver Proof vs Clad Proof — Does It Matter?
Yes, it matters quite a bit. The U.S. Mint offered two versions of the 2010-S Yellowstone Quarter in proof sets — a standard clad version (copper-nickel) and a silver proof version made of 90% silver.
The silver proof is generally more valuable, especially in top grades. Beyond the numismatic value, the silver content alone gives it intrinsic metal value that the clad version simply doesn’t have.
To tell them apart, look at the edge of the coin. A clad coin will show a copper-colored stripe running through the edge. A silver proof will have a solid silver edge with no visible layering. You can also check original packaging if you still have it — the silver proof sets were sold separately at a higher price.
CoinHix is a great tool to quickly compare both versions side by side and track current market values without needing to dig through multiple auction sites.
Mint Mark Location and How to Spot the Real Thing
The mint mark on the 2010-S Yellowstone Quarter is located on the obverse (the heads side) of the coin, just to the right of George Washington’s portrait. It’s a small “S” and easy to miss if you’re not looking for it.
Proof coins from San Francisco are generally well-struck with sharp details and a mirror-like field. The cameo contrast — where the raised design appears frosty white against a reflective background — is especially beautiful on high-grade examples.
If your coin looks dull, scratched, or worn, it may have been removed from its original packaging, which significantly reduces collector value. Original government packaging or a certified slab from PCGS/NGC is the best way to preserve and prove the coin’s condition.

Should You Get It Graded or Just Sell It As-Is
If you have a 2010-S Yellowstone Quarter still in its original U.S. Mint proof set packaging, the best move is usually to keep it that way. Removing a proof coin from its holder can instantly reduce its value in the eyes of collectors.
However, if you think you have a high-grade example — especially a possible PR70 — getting it professionally graded by PCGS or NGC could increase its value significantly. Grading fees typically run $20–$40 per coin, so it only makes financial sense for coins you believe are truly top-tier.
