Did you know that a single dime could be worth a fortune? Some of the rarest U.S. dimes have sold for thousands—or even millions—at auctions.
These coins may seem ordinary at first glance, but their rarity and history make them highly valuable.
In this guide, we’ll explore three of the most valuable dimes ever minted: the 1894-S Barber Dime, 1916-D Mercury Dime, and 1975 No-S Roosevelt Dime. If you have any of these in your collection, you might be holding a hidden treasure!
Overview of the Most Valuable Dimes
| Dime | Year | What Makes It Special | Estimated Value |
|---|---|---|---|
| 1894-S Barber Dime | 1894 | Only 24 minted, fewer than 10 exist today | Up to $1.99 million |
| 1916-D Mercury Dime | 1916 | Low mintage (264,000), “D” Denver mintmark | Up to $100,000+ |
| 1975 No-S Roosevelt Dime | 1975 | Minting error with missing “S” on proof coins | Up to $456,000 |
1. The Legendary 1894-S Barber Dime
The 1894-S Barber Dime is one of the rarest and most valuable coins in U.S. history. It was minted in San Francisco in 1894, with only 24 dimes ever produced. Today, fewer than 10 are known to exist, making this coin a true legend in numismatics.
The story behind this dime remains a mystery. Some believe it was minted as a gift for influential figures, while others think it was struck to balance accounting records at the San Francisco Mint.
If you happen to find this dime in your collection, look for the “S” mintmark on the reverse and the year 1894. A well-preserved example of this coin sold for a staggering $1.99 million in 2016!
2. The Coveted 1916-D Mercury Dime
The 1916-D Mercury Dime is another incredibly valuable coin, known for its low mintage and beautiful design. Designed by sculptor Adolph A. Weinman, this dime features Lady Liberty wearing a winged cap, symbolizing freedom of thought.
What makes it so rare? Only 264,000 of these coins were minted in Denver (“D” mintmark), making it one of the lowest-mintage dimes of the 20th century. Collectors eagerly search for this coin, with circulated versions worth thousands and uncirculated specimens selling for over $100,000.
To check if you have a 1916-D Mercury Dime, look for the small “D” mintmark on the reverse, just below the olive branch. If you spot one, get it appraised—it could be worth a fortune!
3. The Rare 1975 No-S Roosevelt Dime
One of the rarest modern coins ever minted is the 1975 No-S Roosevelt Dime. Normally, proof coins made in San Francisco have an “S” mintmark, but due to a minting error, a few were struck without the “S” mintmark—making them incredibly rare.
So far, only two examples of this error coin have been found, making it one of the rarest U.S. dimes in history. In 2019, one of these dimes sold for $456,000 at auction!
If you own a 1975 proof set, carefully inspect the dimes. If you find one without the “S” mintmark, you could be in possession of an extremely valuable coin.
Why Are These Dimes So Valuable?
Several factors contribute to the high value of these dimes:
- Rarity: Coins with extremely low production numbers or minting errors are highly sought after.
- Historical Significance: Many of these dimes have fascinating stories that make them even more desirable.
- Condition: The better the condition, the higher the value—uncirculated coins can sell for significantly more.
