1881 Liberty Seated Half Dollar. Proof-66 (PCGS).;The centers of this incredible Gem Proof are spotlit by a platinum white brilliance, cooling to a twilight iridescence of violet and sapphire in the peripheries. The fields are glassy and deeply reflective, considerably contrasting the satiny and frosted luster that blankets the design elements. A truly original piece with fully outstanding eye appeal. This coin ranks among the finest pieces certified by PCGS, bested by only a single piece at Proof-67 Cameo.;
