The Roosevelt dime might be one of the smallest coins in your pocket, but certain rare errors have turned this humble coin into a collector’s dream. While most Roosevelt dimes are only worth face value or a bit more in silver, a few minting mistakes have made specific issues worth hundreds or even thousands of dollars. These valuable dimes often go unnoticed by the public because their flaws are subtle to the untrained eye. If you have a stash of old change or a coin collection, it’s time to give your dimes a closer inspection—you might be holding a hidden gem.
1. 1982 No P Roosevelt Dime
One of the most well-known Roosevelt dime errors is the 1982 No P Dime, which was struck at the Philadelphia Mint but missing the “P” mintmark. This was the first year the “P” was routinely included on dimes, making its absence an obvious error. These dimes were accidentally released into circulation before the mistake was caught, and collectors quickly took notice. Depending on condition, a 1982 No P dime can sell for $200 to over $1,000, and high-grade uncirculated examples have reached even higher prices at auction.
2. 1965 Silver Roosevelt Dime
Although dimes struck after 1964 were meant to be copper-nickel clad, a few 1965 dimes were mistakenly struck on leftover 90% silver planchets. These transitional errors are extremely rare and can easily be confused with regular dimes. The best way to check is by weight—silver dimes weigh about 2.5 grams, compared to 2.27 grams for clad dimes. A genuine 1965 silver Roosevelt dime can fetch $3,000 to $7,000, depending on its condition and certification.
3. 1970-S Proof Roosevelt Dime with No S Mintmark
In another stunning mint error, some 1970-S proof Roosevelt dimes were struck without the “S” mintmark, which should have indicated they were produced at the San Francisco Mint. These proof dimes were made for collectors, so the error wasn’t discovered until after sets had already been distributed. Only a small number exist, and they are highly sought after in the numismatic community. These “No S” proof dimes have sold for $500 to $2,000 or more, especially when found in pristine, mirror-like condition.
Roosevelt dimes are often overlooked due to their small size and high mintage, but certain error versions can be worth thousands of dollars. Whether it’s the missing mintmark of the 1982 No P dime, the rare silver transitional error from 1965, or the 1970 No S proof, these mistakes have turned pocket change into serious investments. So before you dismiss those dimes in your coin jar, take a second look—one of them could change your fortune.
