Think a dime is just ten cents? Think again. Some of the rarest dimes in U.S. history are worth thousands—some even millions—of dollars. From historic minting errors to extremely low mintage numbers, these tiny coins can be a hidden goldmine sitting right in your pocket change or coin jar.
Whether you’re a coin collector or just someone cleaning out an old drawer, these are the top 5 dimes you should keep an eye out for—they could be worth up to $2.5 million.
1. 1894-S Barber Dime – The $2.5 Million Collector’s Dream
Estimated Value: Up to $2.5 million
Only 24 of these rare Barber dimes were minted in San Francisco back in 1894—and just 9 are confirmed to exist today. This dime is widely considered one of the most valuable U.S. coins ever struck.
One version sold for nearly $2 million at auction in 2016, and experts believe a pristine example could fetch even more today.
What to Look For:
- The date “1894”
- “S” mintmark on the reverse under the wreath
- Classic Liberty Head design in silver
If you stumble upon this coin in a family collection, don’t spend it—get it professionally appraised immediately.
2. 1969-S Roosevelt Dime with Doubled Die Obverse
Estimated Value: $35,000 – $50,000+
This modern error coin features a doubled die on the front, where text and numbers appear slightly duplicated. It’s subtle but highly prized by collectors.
What to Look For:
- Clear doubling on “LIBERTY” or “IN GOD WE TRUST”
- “S” mintmark indicating the San Francisco Mint
- Sharp, uncirculated condition increases value
Use a magnifying glass—these details are often invisible to the naked eye.
3. 1982 No-P Roosevelt Dime – A Missing Mintmark Mystery
Estimated Value: $500 – $1,500+ (and rising)
In 1980, Philadelphia dimes began carrying a “P” mintmark. So when some 1982 dimes were struck without it, the result was a collectible error. Thousands were made, but few survive in top condition today.
What to Look For:
- The year “1982” with no visible mintmark
- Excellent surface condition (uncirculated is best)
High-grade examples can fetch over $1,000 at auctions or collector shows.
4. 1975 No-S Roosevelt Dime – The Rare Proof Without a Mintmark
Estimated Value: $500,000+
This proof coin was accidentally struck without the required “S” mintmark and ended up in official proof sets sold to collectors. Only two have ever been confirmed, making this dime one of the rarest known errors in modern coinage.
What to Look For:
- Date “1975”
- Proof coin finish (mirror-like shine with frosted details)
- No “S” mintmark despite being a proof
If you have an old proof set from the 1970s, it might be worth taking a second look—you could be sitting on half a million dollars.
5. 1916-D Mercury Dime – Low Mintage, Big Value
Estimated Value: $15,000 – $250,000+
This beautiful dime introduced the famous “Mercury” design (actually Lady Liberty in a winged cap). The Denver-minted 1916-D version is one of the rarest, with only 264,000 coins produced.
What to Look For:
- Date: 1916
- “D” mintmark next to the “E” in “ONE” on the reverse
- Winged Liberty Head design on the front
Condition is everything—a well-preserved coin can easily bring six figures at auction.
How to Know If You Have a Rare Dime
Not every old dime is worth a fortune, but these tips can help you spot a potentially valuable one:
- Use a magnifying glass to inspect dates, mintmarks, and doubling
- Look for unusual details like missing letters or proof finishes
- Weigh the coin—counterfeits may be slightly lighter or heavier
- Never clean the coin—it can drastically reduce its value
- Get a professional appraisal from a certified dealer or grading service like PCGS or NGC
