A tiny mistake at the U.S. Mint can sometimes turn an ordinary coin into a highly valuable collectible. Over the years, some dimes have skyrocketed in value due to mint errors that make them rare and desirable. One such group of dimes, featuring unique mistakes, has collectively sold for a staggering $350,000! If you have old dimes lying around, you might want to check them carefully—you could be holding a hidden treasure.
1. 1968 No S Roosevelt Dime – Sold for $45,000
In 1968, proof coins minted in San Francisco were supposed to bear an “S” mintmark. However, a rare mint error resulted in a batch of 1968 Roosevelt dimes being struck without the “S” mintmark. These error dimes are incredibly scarce, and high-grade specimens have sold for as much as $45,000 at auctions.
2. 1970 No S Roosevelt Dime – Sold for $31,000
Similar to the 1968 dime, the 1970 No S Proof Roosevelt Dime is another rare minting mistake. Only a small number of these were accidentally released without the “S” mintmark, making them highly sought after. One of these dimes, in pristine condition, has been auctioned for an impressive $31,000.
3. 1975 No S Roosevelt Dime – Sold for $456,000
One of the rarest dimes in existence, the 1975 No S Roosevelt Dime is believed to have fewer than 3 known examples. The U.S. Mint mistakenly struck a proof version of this dime without the “S” mintmark, making it one of the most valuable modern dimes ever sold. In a record-breaking auction, one of these dimes fetched an astonishing $456,000!
4. 1982 No P Roosevelt Dime – Sold for $18,000
The 1982 No P Dime is another unusual error where a batch of dimes was struck without the Philadelphia mintmark. Since all dimes from Philadelphia were supposed to feature a “P” mintmark, this error makes the 1982 No P Dime extremely rare. Depending on its condition, these dimes have sold for up to $18,000.
Mint errors may seem like minor mistakes, but they can make a huge impact on a coin’s value. The missing mintmarks on these Roosevelt dimes have turned them into treasures worth hundreds of thousands of dollars. If you own old dimes, take a close look—you might be holding one of these rare coins without realizing it.
