1866 Silver Three-Cent Piece. Proof-65 (PCGS).Richly toned in steel-gray, reddish-russet and charcoal-olive, the reverse is the more boldly patinated of the two sides. Both sport appreciable reflectivity in the fields, and also reveal more vivid undertones as the surfaces dip into a light. Conditionally scarce for a Proof 1866 silver three-cent piece, and of further significance given that the years circulation strike is a key date issue with just 22,000 coins struck.PCGS# 3716. NGC ID: 27CC.From the Collection of James Allaire Millholland, 1842-1911.
