1878 Three-Dollar Gold Piece. MS-64 (PCGS). CAC.A delightful piece worthy of a premium bid, both sides are fully lustrous with a smooth enough texture to suggest a higher grade. Boldly to sharply struck throughout with pretty rose highlights to dominant medium gold patina. The quintessential type candidate in the challenging three-dollar gold series of 1854 to 1889, the 1878 enjoys particularly strong demand in the finer Mint State grades, as here.From The Dr. Andrew Mitchell Collection.
