The 2010 S Yellowstone Quarter is worth anywhere from $2 in circulated proof condition to over $600 for high-grade silver specimens. While your average pocket change might only be worth its face value, some of these special San Francisco-minted issues carry a significant premium for collectors.

Condition / Type	Estimated Value Range
2010-S Clad Proof	$2.00 – $15.00
2010-S Silver Proof	$12.00 – $45.00
Professional High Grade (PR70)	$150.00 – $600.00+

Understanding the 2010 S Yellowstone National Park Quarter

The 2010-S Yellowstone Quarter was the second release in the iconic America the Beautiful Quarters Program. This series, which debuted in 2010, celebrated national parks and sites across the United States. Unlike the P and D quarters you find in your grocery store change, the “S” mint mark indicates the coin was produced at the San Francisco Mint specifically for collectors.

If you have found a shiny 2010 quarter with Old Faithful erupting on the back, the first thing to check is that small mint mark next to George Washington’s ponytail. If you see an “S,” you have a proof coin. Using a top coin identifier app can help you distinguish between the two different metal types minted that year.

Many people use the CoinKnow app to quickly scan their finds and see if they have caught something rare. Because “S” quarters were never released into general circulation, finding one in your change usually means someone broke open a collector set. This “circulated” status slightly lowers the value, but it is still worth more than twenty-five cents.

The Difference Between Clad and Silver Proof Issues

In 2010, the San Francisco Mint produced two distinct versions of the Yellowstone Quarter. The first is the “Clad” version, made of the same copper-nickel alloy as standard quarters. The second is the “Silver” version, which is composed of 90% silver. Identifying which one you have is crucial for determining the price.

The silver version is naturally heavier and has a brilliant white edge rather than the copper stripe seen on standard coins. If you aren’t sure about your coin’s metal content, referencing an updated 2010 quarter value guide can provide the specific weight specifications needed for a scale test.

Metal Composition	Weight	Mintage
Copper-Nickel Clad	5.67 grams	~1,680,000
90% Silver	6.25 grams	~585,000

Determining the Grade and Marketplace Value

Value in the coin world is almost entirely dependent on “grade”—a measure of how many scratches, fingerprints, or scuffs are on the surface. Because proof coins are struck with polished dies, they should have a mirror-like finish. If that finish is dulled or scratched, the value drops to the lower end of the spectrum.

For those looking at high-end investments, the 2010-S Silver Proof in a perfect PR70 Deep Cameo grade is the “holy grail” for this specific year. These perfectly preserved specimens are often sold at specialized auctions for hundreds of dollars. You can check the latest 2010 Yellowstone quarter price trends to see how values have fluctuated over the last few years.

Regular collectors often use the CoinKnow tool to keep a log of their collection’s total worth. Even a common clad proof is worth keeping if it has no visible wear. While you won’t retire on it, a $5 or $10 return on a 25-cent find is still a great win for any casual hunter.

Yellowstone Quarter Design Details and Rarity

The reverse of the coin, designed by Gary Whitley, features the famous Old Faithful geyser with a mature bison in the foreground. This imagery is deeply nostalgic for many Americans who have visited the park, making it one of the more popular designs in the America the Beautiful series.

Mintage numbers for the 2010-S Yellowstone are relatively low compared to the billions of coins struck in Philadelphia or Denver. With only about half a million silver proofs made, they are considered semi-scarce. If your coin has a “satin finish” or shows “Deep Cameo” (where the fields look like mirrors and the devices look like frosted white), you have a premium item.

Condition Grade	Clad Value	Silver Value
PR 65 (Standard)	$3.50	$15.00
PR 69 (Near Perfect)	$12.00	$25.00
PR 70 (Flawless)	$45.00	$425.00+

Tips for Identifying Errors on 2010 Quarters

While errors are much more common on “business strike” coins from Philadelphia or Denver, proof coins can occasionally have rare slip-ups. Collectors look for “Double Dies,” where the letters or numbers appear blurry or doubled. On the Yellowstone design, check the words “Yellowstone” and “Wyoming” carefully under a magnifying glass.

If you suspect you have an error, the CoinKnow app can help you compare your coin against known error databases. An error on an “S” mint coin is extremely rare because the San Francisco mint uses a much stricter inspection process. Finding a verified error could easily triple or quadruple the values listed above.

Always handle your 2010-S quarter by the edges. The oils from your skin can permanently damage the mirror finish of a proof coin, significantly reducing its resale value. If the coin is currently in a plastic case or holder, leave it there!

FAQ

Q: Can I find a 2010-S Yellowstone Quarter in my pocket change?

A: While it is possible, it is very rare. San Francisco Mint quarters were sold directly to collectors in sets. If you find one in change, it was likely spent by someone who didn’t realize its value, and it will probably show signs of wear and tear.

Q: How do I know if my 2010-S quarter is silver?

A: Check the edge of the coin. If you see a solid silver-colored edge with no copper stripe, it is likely the 90% silver version. You can also weigh it; the silver version weighs 6.25 grams, while the clad version is lighter at 5.67 grams.

Q: Is the 2010-S Yellowstone Quarter a good investment?

A: High-grade silver proofs (PR70) have shown steady value over the years. However, common clad proofs usually stay within the $2 to $10 range. They are great for hobbyists but usually aren’t considered high-yield financial investments.

Q: Where is the best place to sell my 2010-S Quarter?

A: For common “S” quarters, online marketplaces like eBay are best. For high-grade coins certified by PCGS or NGC, you might consider a professional coin dealer or a specialized numismatic auction house to ensure you get the best price.
