Sometimes, the most valuable treasures are the easiest to overlook—like a small dime in your pocket or coin jar. While most dimes are worth only ten cents, some contain rare minting errors that can make them worth thousands. These coins often go unnoticed in everyday change and collections, hiding in plain sight until a sharp-eyed collector spots the mistake. Here are three rare error dimes that could be lying right under your nose—if you know what to look for.
1982 No P Roosevelt Dime
One of the most famous modern error dimes is the 1982 No P Roosevelt Dime, struck at the Philadelphia Mint. This coin is missing the usual “P” mint mark, due to a minting mistake. Only a small number were released before the error was caught. If you find one in good condition, it could be worth $200 to $2,000 or more depending on grade. Check any 1982 dime closely—especially if it has no mint mark.
1968-S No S Proof Dime
The 1968-S No S Proof Dime is a very rare error that occurred when some proof dimes made at the San Francisco Mint were struck without the “S” mint mark. These were meant for collector sets, but a few were released with the mint mark accidentally omitted. This error is extremely valuable, with prices reaching $15,000 or more. Since these are proof coins, they’ll have a shiny, mirror-like surface—making them stand out even more.
1996-W Roosevelt Dime
Although not technically an error, the 1996-W Roosevelt Dime is often mistaken for one due to its unique mint mark. It was produced only in a special Mint Set and marked with a “W” for the West Point Mint. Since it was never intended for circulation, finding one in your change is incredibly rare. These dimes can sell for $20 to $100 or more, depending on condition. A W mint mark on a dime is always worth a closer look!
A Simple Dime Could Be a Valuable Discovery
Rare error dimes like these prove that big value can come in small packages. Whether it’s a missing mint mark, a limited proof, or a special release, these dimes are out there—and some are still being found by everyday people. Take a few minutes to check your change, especially older coins. That tiny ten-cent piece could be worth thousands if it has one of these rare errors.
