1880-S Liberty Head Half Eagle. MS-63+ (PCGS). CAC. Splendid honey-rose surfaces are sharply struck from the dies with a full endowment of frosty mint luster. The 1880-S is the first San Francisco Mint half eagle issue with a mintage of more than 1 million coins (1,348,900 pieces, to be exact), and it is popular for type purposes in attractive Choice Mint State preservation, as here.
