1885-O Morgan Silver Dollar, Approximately Very Good Condition. When a U.S. government "hoard" of Morgan silver dollars was discovered in the 1960s, a large number of 1885-O Morgans were included. This has kept the 1885-O, bearing the historic "O" mint mark of the New Orleans Mint, attractively priced even in Uncirculated condition! If you want to own a higher grade silver dollar with the popular "O" mint mark, this is an excellent opportunity to add some "southern charm" to your collection
