The lucky dime was sold in a Heritage Auctions sale on Sept. 6, 2019, according to the Coin World website. Before that, it hadn’t been on an auction floor in eight years.
Five days after it sold, the buyers turned around and sold it again for even more money — $516,000, a new record — to a Roosevelt dime collector.
Before you go digging around in search of a 1975 dime, you should know this: Your chances of having the rare dime are about 1 in 1.4 million.
There are a couple of reasons it is so valuable. First, it has no “S” above 1975 (hence the name), which means it’s an error coin.
And second, this error might have been deliberate, meaning that whoever caused the error would have only done so to a minimal number of dimes.
Only two of the 1975 “No S” Roosevelt dimes coins have knowingly been discovered — and that’s out of more than 2.8 million Proof sets the U.S. Mint produced in 1975.
According to Coin World, the 1975 No-S Roosevelt dime is “chronologically flanked” by several other No-S Proof coins that were created during the same era.
