1870-CC Liberty Seated Silver Dollar. OC-3. Rarity-5+. EF Details--Environmental Damage (PCGS). Plenty of bold to sharp striking detail remains to tempt the budget minded Carson City Mint enthusiast. The surfaces are fairly dark charcoal-gray with a rough, pitted texture to explain the PCGS qualifier. More affordable, yet still desirable Extremely Fine quality for this historic first year silver dollar issue from the Carson City Mint.
