1858 Three-Dollar Gold Piece. AU-55 (NGC).This is a boldly defined, satin to modestly semi-prooflike example with appealing medium gold patina throughout. The rarest Philadelphia Mint three-dollar gold piece from the 1850s, the 1858 has a paltry mintage of 2,133 circulation strikes, and unlike some other three-dollar gold issues, this one saw heavy circulation. Few pieces were set aside and as a result, Mint State pieces are rare today. This example with above average surface preservation is sure to receive the attention it deserves from astute gold collectors.NGC Census: 22; 34 finer, only nine of which are Mint State (MS-63 finest).
