Ron Guth: The 1882-O Silver Dollar is a common date but, because it comes from the New Orleans Mint, it is difficult to locate in Gem condition. The typical Mint State grade for an 1882-O Morgan Dollar is MS-63, reflective of the typical poor strike associated with this mint. Almost 700 MS-65 examples have been certified by PCGS (as of July 2012), but high collector demand means they can be elusive and expensive. MS-66 examples are super-scarce and anything better is ultra-rare. The finest example certified by PCGS is a single, monstrous MS-68 formerly in Jack Lee's set.
