1881 Liberty Seated Quarter. Proof-65 (PCGS). CAC. Splendid originality takes the form deep sapphire blue iridescence draped over dove-grey surfaces, with the left obverse appearing particularly radiant under a light source. Free of detracting blemishes, as befits the Gem grade from PCGS, this lovely proof comes down to us from a mintage of just 12,975 Seated Quarters bearing the 1881 date. From the Harrington Collection.
