What This Coin Looks Like (Obverse, Reverse, Mint Mark Location, Special Features, etc.): One major variety is the 1882-O/S Morgan Silver Dollar. This variety features a New Orleans "O" mintmark struck over a San Francisco "S" mintmark. The dies were originally designed for the San Francisco Mint and were altered to depict the New Orleans Mint Mark instead. This variety can be identified by noticing how the central portion of the "S" is visible inside the "O" as depicted above in the example image.
