1831 William IV Bronzed Copper Proof Penny NGC PR65

William IV bronzed copper Proof Penny 1831, KM707a, S-3845, Peck-1457. No initials on truncation, coin rotation. From the William IV coronation coin set. Immensely glossy, featuring maroon-tinged brown surfaces, the lightness of color over the King's bust lending a visual quality not entirely unlike a cameo effect. Very RARE
