U.S. Mint Coin proof sets are a treasured cornerstone for any numismatic collection. With their unique design and official Certificate of Authenticity, they create beautiful gifts and wonderful keepsakes.
In order to create the coins sharp relief and a mirror-like background, the US Mint's specialized proof minting process requires manually feeding burnished coin blanks into presses where each coin is struck multiple times so the softly frosted and highly detailed images seem to float above the field. The coins are then packaged in a protective lens to showcase and maintain their exceptional finish.
