U.S. Proof Coin Sets (1936-Date)
United States proof coins are extraordinarily brilliant, with sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special cameo effect. Proof blanks are specially treated, polished and cleaned to ensure high quality strikes. The blanks are then fed into presses fitted with hand-polished dies and struck at least twice to ensure sharp relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish!
