1888 Liberty Seated Quarter. Proof-66 (PCGS). CAC. This lovely Gem sports deep peripheral toning in shades of cobalt blue and violet, revealing bright iridescent gold hues at the centers. Beautiful Proof surfaces are boldly defined and offer an uncommonly smooth appearance for a survivor of this 832-piece issue. It is a beautiful coin, made even more desirable by the low circulation strike mintage of the 1888 Liberty Seated quarter. Approval by CAC and provenance to the famous Benson Collection surely adds further appeal. From the Harrington Collection. Earlier ex Ira S. Reed, February 26, 1944 for $3.00; the Goldbergs sale of the Benson Collection, February 2002, lot 754.
