They are located on the back of the Morgan dollar, beneath the eagle's tailfeathers, and refer to the mint at which the coin was produced: "O" for New Orleans, Louisiana; "S" for San Francisco, California, and "CC" for Carson City, Nevada. Coins without a mintmark were produced in Philadelphia, Pennsylvania.
