1942 finally sees another error worth big dollars. The error is known as the “42 over 41”. This is known as an “Overdate” error. A 42 was stamped over a 41. When looking at the dime, you can see the error.

If you find the 1942 Mercury Dime with the “42 over 41” Overdate error, either the non-minted Philadelphia version or the 1942-D, you’re sitting on a potentially decent high value coin. The non-mintmark Philadelphia version will likely get you upwards of $15,000 (Based on Red Book) and the Denver mintmark Mercury dime could potentially fetch $10,000 at auction. The standard variety of this years mintmarks in MS-63 condition will only get you $12. That error is the real win if you can find it!
