In the world of coin collecting, tiny mistakes can lead to massive payouts. One such error from the 1970s is making waves today—a simple misstep at the U.S. Mint has turned an ordinary-looking dime into a fortune. A 1970s Roosevelt Dime with a rare mint error recently sold for $400,000, shocking collectors and casual enthusiasts alike. If you’ve got spare change lying around, this might be your sign to take a closer look.
1970-S Proof Roosevelt Dime No S Mint Mark
The star of the story is the 1970-S Proof Roosevelt Dime without the “S” mint mark. While proof coins from San Francisco typically carry the “S” designation, a small number of 1970 dimes were mistakenly struck without it. These coins were intended only for collector sets, making this mint error exceptionally rare. Only a few known examples exist, and one in pristine condition recently sold for $400,000 at auction. The lack of the mint mark makes this coin one of the most desirable modern-era errors.
1982 No P Roosevelt Dime
Another highly valuable dime is the 1982 No P Roosevelt Dime, which was struck in Philadelphia without the “P” mint mark. This was the first time in modern U.S. coinage history that such an error occurred. The Philadelphia Mint began using the “P” mint mark in 1980, but a limited batch of 1982 dimes was mistakenly minted without it. These errors are found only in certain batches from early in the year. In top condition, they can fetch $1,000 to $20,000, depending on grade and rarity.
1968 No S Roosevelt Proof Dime
Similar to the 1970 error, the 1968 No S Roosevelt Proof Dime is another shocking mistake. Proof coins from San Francisco are supposed to carry the “S” mint mark, but a few 1968 dimes were struck without it. This was one of the earliest major “No S” mint mark errors, and the coin’s value skyrocketed as collectors realized how few existed. Today, one of these coins in perfect condition can bring in $25,000 to $35,000, with even lightly circulated examples worth several thousand dollars.
Mistakes at the mint are rare—but when they happen, they can lead to unbelievable profits. The 1970-S No S Dime, 1982 No P Dime, and 1968 No S Proof Dime show that tiny details can make a massive difference in value. While most dimes are worth only 10 cents, these unique errors are worth thousands—sometimes hundreds of thousands—thanks to limited circulation and high collector demand. It’s always worth checking your change or old coin sets. One lucky find could change your financial future.
