The 1970-S No S Proof Roosevelt Dime is a fascinating rarity in the world of numismatics. This intriguing coin, the result of a minting error, lacks the customary “S” mint mark that signifies production at the San Francisco Mint. Though intended for collectors, some of these dimes have surprisingly entered circulation, making them an unexpected treasure for those lucky enough to find one. With values reaching up to $1,300, this coin remains a highly sought-after piece for numismatists.
The Origins of the 1970-S No S Proof Roosevelt Dime
The Roosevelt Dime has been a part of U.S. coinage since 1946, honoring President Franklin D. Roosevelt and his efforts to combat polio through the March of Dimes. Proof versions of this coin are meticulously crafted with a mirror-like finish and intricate details, typically displaying an “S” mint mark when minted in San Francisco.
However, in 1970, a small number of these proof dimes were mistakenly struck without the “S” mint mark. While these coins were originally included in proof sets sold to collectors, some eventually found their way into general circulation. This unintentional release has made them one of the rarest and most intriguing error coins in U.S. history.
