1876 Twenty-Cent Piece. Proof-64 (NGC). Boldly and originally toned over fully impressed, satin to semi-reflective surfaces. At 1,500 pieces produced, the 1876 boasts the highest mintage in the Proof twenty-cent series of 1875 to 1878. The Mint undoubtedly stepped up production of Proof coinage this year in anticipation of strong sales in connection with the United States centennial. While survivors of this issue are plentiful by the standards of the type, few have been as nicely preserved as this handsome near-Gem. PCGS# 5304. NGC ID: 27H3.
