1872 Liberty Seated Half Dollar. Proof-64 (PCGS).，Multicolored peripheral toning on the obverse yields to more reserved smoky gray patina in most other areas, although we do note glints of pinkish-copper iridescence here and there around the reverse border. A smartly impressed, nicely preserved near-Gem from a Proof mintage of 950 pieces. Our extensive offerings in this sale notwithstanding, the Proof Motto Liberty Seated half dollars of 1866 to 1878 are generally scarcer than their more eagerly sought counterparts struck from 1879 through the series end in 1891. This vivid and appealing 1872 represents a significant find for the astute bidder.，PCGS# 6430. NGC ID: 27U7.，，From the Alexander Collection.
