1857-C Gold Dollar. AU-50 (NGC).Blended olive-khaki and honey-gold patina greets the viewer from both sides of this overall sharply defined example. The penultimate Charlotte Mint gold dollar, the 1857-C was produced to the extent of just 13,280 coins. While this is actually one of the more frequently encountered C-mint gold dollars in an absolute sense, it is also one of the scarcest in high grades. Since it is more readily obtainable than the 1859-C -- the only other Charlotte Mint gold dollar of the Type III design -- pleasing AU examples of the 1857-C, as here, rarely remain on the open market for long.
