United States Mint proof coins are extraordinarily brilliant with sharp relief and a mirror-like background. The proofing process results in coins that feature frosted, sculpted foregrounds, giving them a "cameo" appearance. 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 two times to ensure sharp, high relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish.
