1887/6-O $1 Morgan Silver Dollar PCGS MS63

NGC Coin Explorer reports, "The 1887/6 Morgan dollar varieties were created when 1886 dies had the last digit of the date removed and replaced with a 7. However, the mint worker did not completely remove the 6, leaving a trace of the bottom loop. This created a couple of the most popular varieties in the entire Morgan dollar series." PCGS has graded 352 in MS63 with 191 finer.

David Bowers writes (in 1993): "The 1887/6-O overdate was discovered by professional numismatist Bob Riethe in 1972, a year after Ted F. Clark's discovery of the Philadelphia version. Little attention was paid to the 1887/6-0 in the early years, but beginning with the dissemination of information from the Van Allen-Mallis book, and, more recently, the Fivaz-Stanton guide, interest has increased sharply.

The overdate is not as sharp as the 1887/6 Philadelphia coins, and in later states is very faint and quite difficult to immediately discern. The best advice for the collector is to cherrypick for quality and seek an early die impression.

Probably many regular 1887-O coins await identification as overdates, as the variety has not been widely publicized. However, like its Philadelphia Mint counterpart, it has been listed in the Guide Book for several editions."
