What this coin looks like (obverse, reverse, mint mark location, special features, etc.):
The 2012-S "Reverse Proof" American Silver Eagle was produced at the San Francisco Mint using a highly innovative and technologically advanced minting process - which resulted in a coin with a frosty satin background field (like normal uncirculated silver eagles) but the details and designs have brilliant mirror-like features. This coin also bears the "S" mint mark.
This coin was intended for a 2-coin American Silver Eagle set commemorating the 75th anniversary of the San Francisco Mint. The set contained a 2012-S Proof and Reverse Proof coin - and each set originally sold for $149.95.
