Is Your 1968 ‘No Mint Mark’ Roosevelt Dime Worth Nearly $20,000?

The common ten-cent coin of the Roosevelt dime (1968) depicts the Franklin D. Roosevelt image as part of the obverse and a torch, olive, and oak branches as part of the reverse.

However, some of the 1968 dimes have become very valuable due to their scarcity. This occurs due to a minting error, where the ‘S’ mint mark indicating the coin was produced at San Francisco Mint is missing. So, the ‘No S’ dimes are valuable among coin collectors, attaining a price of up to $45,600 at auction.

There was, however, an accident in which a small number of proof dimes were created without the ‘S’ mark. Thus came to be the extremely rare ‘No S’ version.

The exact quantity of these error coins is not known. However, it is estimated that only a few dozen exist today, making it an important find for any coin collector.
