The 1890-O Morgan dollar is a very common coin in all circulated grades and in MS levels through MS64, though above that this piece becomes exceptionally tough. It is rare in MS66 or better, with decent bidding wars often waged between registry set collectors who want the best pieces for their collections. PLs and DMPLs are scarce in all grades and rare in the Gem levels.
