The Library of Congress Commemorative Coins were authorized in Public Law 105-268 to commemorate the new Millennium and the Bicentennial of the Library of Congress. Congress approved the Mint to make up to 200,000 $10 bi-metallic coins and 500,000 $1 silver coins.
These commemorative coins are called the coins of many firsts. The first commemorative coins of the new Century, they are also the first-ever gold and platinum bi-metallic coins in the nation's history. For the bi-metallic version, the outer ring is stamped from a sheet of gold, then a solid core of platinum is placed within the ring. The coins contain about one-half an ounce of precious metal.
The bi-metallic obverse coin features the hand of Minerva, Roman goddess of wisdom, holding the Torch of Learning with the Jefferson building dome in the background. The reverse shows the Library's seal encircled by a laurel wreath.
