The American Eagle Silver Proof Coin is a collector version of the official United States Mint American Eagle Silver Bullion Coin. Each coin contains one ounce of .999 fine silver. United States Mint proof coins are extraordinarily brilliant, with sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special cameo effect. Proof blanks are specially treated, polished and cleaned to ensure high-quality strikes. Each coin also bears the “W” mint mark reflecting its striking at the United States Mint facility at West Point. Each coin is packaged in a blue velvet, satin-lined presentation case and accompanied by a Certificate of Authenticity.
