1860-O Liberty Seated Silver Dollar. OC-4. Rarity-2. MS-63 (PCGS).Satiny surfaces are brilliant apart from wisps of pale silvery iridescence that are not readily evident at all viewing angles. Although the Treasury Department releases of the early to mid 1960s have made the 1860-O one of the most readily obtainable Liberty Seated dollars in Mint State, most such examples found therein are heavily abraded and grade no finer than MS-62 by todays standards. A find for the better-quality type collector.PCGS# 6950. NGC ID: 24Z3.
