1885 Liberty Seated Half Dollar. Proof-66 (NGC). CAC. Thoroughly appealing premium Gem quality from an issue of 930 Proofs. The surfaces are painted in an original patina of varying peach and violet hues. This patina explodes with vibrant purple and electric blue iridescence under direct lighting. Light reflectivity in the fields frames sharp and satiny devices. The 1885 is one of the lowest mintage dates in the extensive Liberty Seated half dollar series, circulation strike production for the year confined to the Philadelphia Mint and amounting to just 5,200 pieces. Just 10 coins have been certified finer by NGC in this category. From the Harrington Collection.
