The United States Mint produces proof and uncirculated versions of American Eagle and Buffalo Bullion coins with Liberty featured on the obverse, for collectors. American Eagle Proof Coins undergo a specialized minting process, which begins by manually feeding burnished coin blanks into presses fitted with special dies. The coin is struck multiple times so the softly frosted, yet detailed images seem to float above a mirror-like field. After scrutiny by white gloved inspectors, each American Gold Proof Coin is sealed in a protective plastic capsule and mounted in a handsome satin-lined velvet presentation case with its own official Certificate of Authenticity. Since American Eagle Proof Coins are produced by the United States Mint, each coin's content, weight and purity are guaranteed by the United States Government. American Eagle Gold, Silver, and Platinum Proof Coins have a limited mintage.
In a process similar to that used to create the magnificent American Eagle Proof Coins, American Eagle Uncirculated Coins are hand-loaded into the coining press, struck on specially burnished blanks and carry the "W" mint mark of the United States Mint at West Point.
