Old Silver US Coins. 1890 Morgan Dollar Royalty-Free Stock Photo

Old Silver US Coins. Morgan silver dollars, all composed of 90% silver and 10% copper slightly less silver than sterling silver, were struck between 1878 and 1904, with a final minting in 1921. The 1921-dated coins are the most common, and there exists a substantial collector market for pristine, uncirculated specimens of the rarer dates and mint marks. Morgan dollars are second only to Lincoln Cents in collector popularity. The coin is named after George T. Morgan, its designer. Morgan dollars were minted at Philadelphia no mint mark, New Orleans `O` mint mark, San Francisco `S` mint mark, Carson City `CC` mint mark, and in 1921 only Denver `D` mint mark. The mint mark is found on the reverse below the wreath, above the `O` in `DOLLAR`.
