1890 Liberty Seated Quarter. Proof-67 (PCGS). CAC.；The beautifully toned obverse features a blend of antique copper and electric blue, while the reverse is awash in bolder copper-mauve patina -- very attractive. The strike is sharp, the finish is intensely reflective and the surfaces are virtually pristine. This coin is one of the finest certified survivors from a mintage of 590 Proof quarters for the date. Superb!；From our (Stacks) sale of the S.S. Forrest, Jr. Collection, September 1972, part of lot 893.
