1855 Liberty Seated Silver Dollar. OC-1. Rarity-3+. Fine Details--Tooled (PCGS).Circulation strike silver dollars of the mid to late 1850s were used primarily in export trade, and these coins can be seen as predecessors to the specialized trade dollar introduced in 1873. With most of the 26,000 circulation strikes produced melted or otherwise lost overseas, this issue is understandably elusive in todays market. A more affordable example, the significance of this coin for the budget minded collector can hardly be overstated.PCGS# 6943. NGC ID: 24YU.From the Collection of Silas Stanley Roberts, 1888-1966.
