The numismatic world was recently captivated by the sale of a 1975 Roosevelt dime for a staggering $506,250 at auction. What sets this dime apart is not what’s present, but what’s missing—a mint mark. This coin lacks the ‘S’ mint mark typically found on proof coins produced at the San Francisco Mint, making it one of only two known examples. This rare error has elevated the dime to legendary status in American coin collecting.
Understanding the Rarity of the 1975 ‘No S’ Dime
In 1975, the San Francisco Mint struck approximately 2.84 million proof sets, each coin bearing the distinctive ‘S’ mint mark. However, a minting error led to the production of two dimes without this mark. Such a small detail might seem insignificant, but it has turned these dimes into some of the most coveted modern coins in American numismatics.
The Discovery and Early Sales
The two known specimens of the 1975 ‘No S’ dime were discovered in California during the late 1970s. Dealer F.J. Vollmer acquired both coins, with the first selling in 1978 for $18,200, an extraordinary amount for the time. The buyers, an Ohio collector and his mother, held onto the coin for decades, proving that patience can yield incredible returns in the rare coin market.
A Record-Breaking Auction
The recent auction, hosted by GreatCollections in October 2024, drew over 200 bids from collectors worldwide. Graded PCGS Proof-67 and approved by the Certified Acceptance Corporation (CAC), the dime achieved its record-breaking price of $506,250, setting a new benchmark for this modern mint error.
