For coin collectors, finding a rare and valuable dime is like striking gold. Whether tucked away in an old drawer or passed down through generations, certain dimes hold immense historical and monetary value. The rarity of a coin often depends on limited mintage, minting errors, or unique historical significance.
Among the rarest U.S. dimes, three stand out for their incredible value and scarcity: the 1894-S Barber Dime, the 1916-D Mercury Dime, and the 1975 No-S Roosevelt Dime. These coins have fetched thousands, even millions, at auctions, making them a dream find for any numismatist.
If you’re a collector or just someone with a handful of old dimes, here’s why you should keep an eye out for these three gems.
1. 1894-S Barber Dime – The Million-Dollar Coin

The 1894-S Barber Dime is one of the most legendary and valuable dimes in existence. Minted at the San Francisco Mint in 1894, only 24 pieces were produced, and today, just nine are known to exist.
Why is it so rare?
Several theories surround the coin’s scarcity. Some experts believe it was struck as a special gift for bankers or prominent individuals. Others suggest that it was part of a failed test run. Regardless of the origin, the 1894-S Barber Dime has become one of the most sought-after coins in the world.
Value & Auction Records
- One of these dimes sold for $1.9 million at auction in 2007.
- Another was reportedly purchased for $2 million in a private sale.
How to Identify It?
- Features Lady Liberty wearing a Phrygian cap with “United States of America” inscribed around her.
- The reverse displays a wreath surrounding “One Dime.”
- If the dime has an 1894 date with an “S” mint mark below the wreath, it could be a multimillion-dollar coin.

2. 1916-D Mercury Dime – The Rarest of Its Kind

The 1916-D Mercury Dime is another rare find, notable for its extremely low mintage. The Denver Mint produced only 264,000 of these dimes, making it the scarcest dime in the Mercury series.
Why is it so valuable?
- It was the first year the Mercury Dime was introduced, replacing the Barber Dime series.
- Due to low production numbers at the Denver Mint, few survived in mint condition.
Auction Prices & Market Value
- A high-grade MS-67 condition 1916-D Mercury Dime sold for $207,000 at auction.
- Even worn-out versions fetch thousands, depending on their grade.
How to Identify It?
- Features Winged Liberty (often mistaken for Mercury, the Roman god) on the front.
- The Denver mint mark (“D”) is located on the reverse, near the base of the torch.
- The 1916 date should be clearly visible with no signs of tampering.
Collectors can check authenticity with certified coin grading agencies like the Professional Coin Grading Service (PCGS): www.pcgs.com.
3. 1975 No-S Roosevelt Dime – The Minting Error That Turned to Gold

The 1975 No-S Roosevelt Dime is an unusual rarity caused by a minting error. While the San Francisco Mint produced millions of proof dimes in 1975, a small number (only two known to exist) were mistakenly struck without the “S” mint mark.
What makes it unique?
- Proof coins from San Francisco should always carry an “S” mint mark.
- These missing-mint-mark dimes were never meant to enter circulation.
- Most were likely caught before release, making the surviving examples incredibly rare.
Record-Breaking Sales
- One example sold for a staggering $456,000 in 2019.
How to Spot It?
- The front displays Franklin D. Roosevelt’s profile (same as regular dimes).
- The reverse features an olive branch, torch, and oak branch.
- The key difference: No “S” mint mark below the year 1975.
To verify rare mint errors, collectors can consult the Numismatic Guaranty Company (NGC): www.ngccoin.com.
