Legend says that the San Francisco Mint superintendent, knowing the coin would be exceptionally rare, gave three of them to his daughter to keep. There's a charming story about this coin that may or may not be true. Although it was a proof coin, a few ended up in circulation, including one that showed up in 1957 at Gimbels Department Store in New York City. The dime features Lady Liberty in profile on the front and a wreath on the back with 'One Dime' stamped in the center.
A proof copy of a coin they didn't end up minting that year, there were originally 24 struck. One of the rarest US coins in existence according PCGS Coin Trackers, the 1894-S Barber dime has only nine known examples today.
