|The 1900-O/CC Morgan Silver Dollar is an interesting over mint mark variety. Presumably, an old reverse die with a CC mint mark was reworked and given an O mint mark for New Orleans. By 1900, the CC reverse dies were no longer needed as the Carson City Mint had stopped minting coins several years prior in 1893. However, after the reverse dies had been reworked with the new O mint mark, clear remnants of the underlying CC mint mark still remained. This example of the 1900-O/CC Morgan Dollar has been graded MS66 by PCGS and is encapsulated in one of the newer-style edge-view holders. This coin is a beautiful high-end example with just a touch of toning along the rims. Very difficult to find examples of this popular variety in such amazing condition.
