1851-O Liberty Head Eagle. AU-58 (NGC).Sharply defined in and around the centers, this medium gold eagle also offers ample luster in a bright satin texture. After the 1847-O, the 1851-O is the most frequently encountered New Orleans Mint eagle of the No Motto design type. Conditionally scarce at the Choice AU level, the present example would do equally well in a mintmarked gold type set or advanced Southern gold collection.
