1881-O Morgan Silver Dollar. MS-66 (PCGS). A brilliant, frosty premium Gem with a sharp strike and exceptionally well preserved surfaces. As with so many Morgan dollar deliveries, the 1881-O is plentiful in lower Mint State grades but scarce to rare any finer than MS-65. Premium quality both in terms of striking quality and surface preservation, this impressive MS-66 is among the finest known to PCGS and is seemingly earmarked for inclusion in an advanced collection of this widely collected series.
