1900 O over CC Morgan Silver Dollar. Mint: New Orleans. Mintage: UNKN. Weight 26.73 grams, 0.900 fine silver, 0.7734 oz. ASW. Very Scarce Variety Coin When it became evident that the Carson City Mint would coin no more silver dollars after July 1, 1899, and old dies on hand were returned to Philadelphia, at least six Morgan dollar reverse dies with the CC mintmarks on them were partly effaced in the mintmark area and over punched with 0 mintmarks. Can any of the dies be specifically identified as having been used for 1893-CC or other CC coinage. it is at first glance an ordinary Morgan-type silver dollar of 1900 from the New Orleans Mint, but upon closer examination of the mintmark it has the appearance of the O having been punched in over the letters CC. If this is so, then, undoubtedly, in this instance a reverse die was taken from the Carson City Mint to the mint at New Orleans [sic; actually the punching was done in Philadelphia], where the usual O was punched in the die over the CC and used in conjunction with an obverse die of 1900.
