According to PCGS: Understanding the extreme rarity of the 1975 “No-S” Proof Dime is enormously valuable!
In 1975, the San Francisco Mint made a mistake that turned out to be one of the most expensive modern coins ever. They made a dime without a mint mark, which was discovered in a 1975-S Proof Set. A second example was also found years later. Neither coin had ever appeared at auction until the discovery coin was included in the 2011 sale by Stack’s-Bowers. The 1975 No-S Roosevelt dime sold for over $300,000 in 2011. But wait, there’s more! On September 6, 2019, this same 1975 dime sold for $456,000 at auction. Then, less than 1 week later, it sold to a dime collector for $516,000. That’s right, over half a million dollars for a dime!
The “No-S” Proof coins were the product of the way in which Proof dies were handled. Beginning in 1968, when the San Francisco Mint began striking Proof coins, all dies for Proof coins were prepared at the Philadelphia Mint. This was done by adding a mintmark to a normal P-Mint die. However, some dies escaped this process, thus we see “No-S” dimes in 1968, 1970, 1975, and 1983. Any estimates of the number of “No-S” coins is strictly a guess.
And that’s the story of the 1975 No S Roosevelt Dime, a rare coin that is worth a fortune!
