The 2010-S Yellowstone Quarter is worth anywhere from $2 in average condition to over $15 or more for top-grade proof specimens. If you’ve come across one of these beautiful coins and you’re wondering whether it’s a keeper or just a spender, you’re in the right place — this guide breaks it all down in plain English.
What Is the 2010-S Yellowstone Quarter?
The 2010-S Yellowstone Quarter is part of the America the Beautiful Quarters Program, a series launched by the U.S. Mint to honor national parks and historic sites across all 50 states, territories, and the District of Columbia. Yellowstone National Park, located primarily in Wyoming, was one of the first five parks featured in 2010.
The “S” mint mark tells you this coin was struck at the San Francisco Mint — and that’s important. The San Francisco Mint doesn’t produce coins for everyday circulation. Instead, it focuses on proof coins, which are specially struck with polished dies to create sharp details and mirror-like finishes. These are made for collectors, not your pocket change.
If you found a 2010-S Yellowstone Quarter, it almost certainly came from a proof set rather than being pulled from a cash register. That already makes it a bit more special than your average quarter.

2010-S Yellowstone Quarter Value by Grade and Type
The value of a 2010-S Yellowstone Quarter depends heavily on its condition and whether it’s a standard clad proof or the rarer silver proof version. The San Francisco Mint made both — the standard version in copper-nickel clad, and a 90% silver version for collectors willing to pay a premium.
Here’s a quick breakdown of current estimated values:
| Coin Type | Grade / Condition | Estimated Value |
|---|---|---|
| 2010-S Clad Proof | PR65 (average proof) | $2 – $4 |
| 2010-S Clad Proof | PR69 DCAM (deep cameo) | $6 – $10 |
| 2010-S Clad Proof | PR70 DCAM (perfect) | $12 – $20+ |
| 2010-S Silver Proof | PR65 | $6 – $9 |
| 2010-S Silver Proof | PR69 DCAM | $12 – $18 |
| 2010-S Silver Proof | PR70 DCAM | $25 – $40+ |

How Mintage Numbers Affect the 2010-S Yellowstone Quarter Value
Mintage is one of the biggest factors collectors consider when determining a coin’s long-term worth. The 2010-S Yellowstone clad proof had a mintage of roughly 3.26 million coins, while the silver proof version came in lower at around 800,000.
Lower mintage generally means more scarcity, and scarcity can drive prices higher over time — especially for top-graded examples. A PR70 Deep Cameo coin is essentially flawless, and only a small percentage of any mintage will ever achieve that rating from professional grading services like PCGS or NGC.
For coins from this era, certified high-grade examples tend to hold or grow in value as the series matures and more collectors complete their sets.
Is the 2010-S Yellowstone Quarter Worth Keeping?
Honestly, yes — especially if it’s in excellent condition and still in its original proof set packaging. A coin that’s been sitting loose in a drawer and shows contact marks is worth considerably less than one that’s been properly stored.
The silver proof version is particularly worth holding onto. With silver prices fluctuating and collector demand steady, these coins offer a small but real store of value beyond face value.

Tips for Selling or Storing Your 2010-S Yellowstone Quarter
If you’re thinking about selling, your best options are eBay, local coin shows, or established coin dealers. For raw (ungraded) coins in average proof condition, expect modest returns. But if you have a coin that looks pristine, it might be worth spending a small fee to have it professionally graded — a PR70 DCAM certification can significantly increase what a buyer is willing to pay.
For storage, keep proof coins in their original packaging whenever possible. If that’s not an option, use acid-free coin flips or a hard plastic holder. Never clean a coin — even gentle polishing can destroy its proof surface and wipe out most of its collector value instantly.
Using CoinKnow before you sell can help you set realistic price expectations and avoid leaving money on the table.
FAQ
Q: How do I know if my 2010-S Yellowstone Quarter is silver or clad?
A: The easiest way is to look at the edge of the coin. A clad coin will show a copper-colored stripe along the rim, while a silver proof will appear uniformly silver all the way around. You can also weigh it — silver proofs weigh 6.25 grams compared to 5.67 grams for the clad version.
Q: Is a 2010-S Yellowstone Quarter worth more than face value?
A: Yes, virtually always. Even a basic clad proof in average condition is worth $2–$4, which is already 8–16 times its 25-cent face value. Silver proofs and high-grade certified examples can be worth significantly more.
Q: Where can I sell my 2010-S Yellowstone Quarter for a fair price?
A: eBay is the most accessible marketplace with the widest buyer pool. For graded coins, major auction houses like Heritage Auctions or Stack’s Bowers are worth considering. Always research recent sold listings before pricing your coin to make sure you’re in line with current market demand.
