United States proof coins are extraordinarily brilliant with sharp relief and a mirror-like surface. Their frosted, sculpted foregrounds give them a special "cameo" effect, created by the exacting proofing process. 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 a sharp, high relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish.
