1. The 1894-S Barber Dime
The 1894-S Barber Dime is legendary in the numismatic world. With only 24 ever minted and just 9 confirmed survivors, it’s one of the rarest coins in U.S. history. Theories abound about why only 24 were produced—some say it was a special minting for banker gifts, others believe it was simply a mistake.
How to Identify:
- Year: 1894
- Mint Mark: “S” under the wreath on the reverse
- Design: Liberty head on the obverse, wreath on the reverse
- Estimated Value: Over $1.3 million
Collectors covet this dime not just for its rarity but also for its backstory, making it a true grail item.
2. The 1975 No S Proof Roosevelt Dime
This modern dime is rare because of a mistake. In 1975, a few proof dimes intended for the San Francisco Mint were struck without the “S” mint mark. Only two have ever been found, making it one of the rarest modern U.S. coins.
How to Identify:
- Year: 1975
- Mint Mark: No “S” on the obverse
- Finish: Mirror-like proof surface
- Estimated Value: Over $500,000
Collectors are still hunting for a third example, so check your proof sets!
3. The 1916-D Mercury Dime
The Mercury Dime, introduced in 1916, is beloved for its artistic design. The 1916-D, however, is prized for its rarity: only 264,000 were minted. Add “Full Bands” (a sharp strike detail on the reverse), and you’ve got a coin easily worth six figures.
How to Identify:
- Year: 1916
- Mint Mark: “D” near the fasces on the reverse
- Design: Liberty with a winged cap
- Estimated Value: Up to $264,000
4. The 1919-D Mercury Dime (Full Bands)
The 1919-D Mercury Dime isn’t rare in general—but one in pristine condition, with Full Bands (well-defined horizontal lines on the fasces), is. The quality of the strike makes a huge difference in price.
How to Identify:
- Year: 1919
- Mint Mark: “D” on the reverse
- Feature: Fully struck horizontal bands
- Estimated Value: Up to $156,000

Whether you inherited a coin collection or enjoy digging through change, here’s what to do:
1. Check the Date and Mint Mark
Look on the obverse and reverse for a mint mark. The year and location of minting are crucial.
2. Inspect for Errors or Missing Marks
Missing mint marks or doubled images are often signs of a rare coin.
3. Look for Strike Quality
Especially for Mercury dimes, “Full Bands” detail on the reverse can drastically increase value.

Coins are graded from Poor (P-1) to Perfect Uncirculated (MS-70). The higher the grade, the more it’s worth.
5. Get it Graded
Use certified grading services like PCGS or NGC for authentication and valuation.
