"The term "proof" refers to a specialized minting process that begins by manually feeding burnished coin blanks into presses fitted with special dies," the U.S. Mint states on its Web site. "Each coin is struck multiple times so the softly frosted, yet detailed images seem to float above a mirror-like field."
