1894-S Barber Dime
The 1894-S Barber Dime is one of the most famous and valuable U.S. coins ever minted. Struck at the San Francisco Mint in 1894, only 24 of these dimes were produced. Today, fewer than 10 are known to exist, making it one of the rarest coins in American history.
The story behind this dime remains a mystery. Some theories suggest that these coins were gifted to influential individuals, while others believe they were minted to balance accounting records at the San Francisco Mint.
Because of its extreme rarity, the 1894-S Barber Dime has reached astounding auction prices. In 2016, one example sold for $1.99 million, proving that this coin is a true collector’s dream.
How to Identify It
- Look for the 1894 date on the front (obverse) of the coin.
- Check the reverse side for the “S” mintmark, which indicates it was minted in San Francisco.
If you ever come across an 1894-S Barber Dime, have it authenticated immediately—you may be holding one of the most valuable coins in the world.
1916-D Mercury Dime
The 1916-D Mercury Dime is another treasure sought after by collectors. Designed by sculptor Adolph A. Weinman, this coin features Lady Liberty wearing a winged cap, symbolizing freedom of thought. Many consider it one of the most beautiful U.S. coin designs.
Only 264,000 of these dimes were minted at the Denver Mint, making it one of the lowest-production dimes of the 20th century. Due to its scarcity, collectors will pay thousands of dollars for this coin—even in worn condition. Uncirculated examples can exceed $100,000 at auction.
How to Identify It
- Look for the 1916 date on the front of the coin.
- Check the reverse side, just below the olive branch, for the “D” mintmark, indicating it was minted in Denver.
If you find a 1916-D Mercury Dime, it’s best to have it professionally appraised—it could be worth a fortune.
1975 No-S Roosevelt Dime
The 1975 No-S Roosevelt Dime is a modern rarity, created due to a minting error at the San Francisco Mint. Normally, proof coins struck in San Francisco bear an “S” mintmark, but in 1975, a few dimes were mistakenly struck without it.
So far, only two examples of this dime have been discovered, making it one of the rarest modern U.S. coins. In 2019, one sold for $456,000 at auction, proving that even small minting errors can turn a coin into a prized collectible.
How to Identify It
- This coin only appears in proof sets from 1975.
- Look for the missing “S” mintmark above the date. If the “S” is missing, you may have one of the rarest dimes in existence.
If you own a 1975 proof set, it’s worth checking the dimes closely—you might have a hidden treasure in your collection.
Could You Have One of These Rare Dimes?
While these coins are incredibly rare, finding one isn’t impossible. Many valuable coins have been observed in old collections, inherited coin sets, and even loose change.
If you come across an unusual-looking dime, check its mintmark, date, and condition. A small coin could turn out to be a million-dollar treasure hiding in plain sight.
