What this coin looks like (obverse, reverse, mint mark location, special features, etc.):
Supposedly no 1870-S Seated Liberty Half Dimes were produced according to the San Francisco Mint but the Mint did have 6 pairs of half dime coin dies all set for production. In 1870: The San Francisco Mint (Granite Lady) was about to be built. US Mint documents did state that some coins would be struck in San Francisco to be used for the cornerstone display. In 1978: A coin collector was going through a "cheap coins" box and purchased an 1870-S half dime from a dealer at a coin show. It was found that this coin really was a genuine production and it is the only 1870-S seated liberty half dime in existence! It is thought that there may be more of them out there and perhaps even in the cornerstone of the old San Francisco Mint. The coin was exhibited at the American Numismatic Association and later sold to a coin dealer John Abbott of Michigan for $425000. In 2009 the coin was sold at a private auction for $1.4 Million.
