1868 Liberty Seated Quarter. Proof-66 Cameo (PCGS). Brilliant in the centers, this lovely specimen exhibits sandy-silver patina around the peripheries that yields to a blush of rich charcoal-blue at the upper obverse border. Highly reflective fields support frosty, fully impressed design elements. This is an outstanding and rare premium Gem Cameo from a mintage of 600 Proof Liberty Seated quarters of this date. From the Francesca Collection.
