1848 Liberty Seated Silver Dollar. OC-1, the only known dies. Rarity-2. AU-50 (PCGS).Lightly toned with swirls of olive patina to a base of antique silver. Plenty of satiny luster remains to tempt the viewer as the surfaces dip into a light. Boldly defined over most design elements, this is a pleasing AU survivor of the low mintage (15,000 pieces) 1848 silver dollar.
