Rounds are basically coin-shaped pieces of precious metal. They are not legal tender, nor do they have a face value; their worth is based solely on their precious metal content so they're popular with investors. However, that's the simple definition - some gold and silver rounds also have considerable numismatic value. Good examples include the American Buffalo and the Bull and Bear from the Sunshine Mint in Arizona and unique coins like the 1987 12oz 200th Anniversary Casa de Moneda de Mexica Platinum Round.
