Certified American Commemorative Gold Coins. The United States Congress authorizes the minting of commemorative coins to celebrate and honor American people, places, events and institutions. Although these coins are legal tender, they are not minted for general circulation.
The Louisiana Purchase Exposition Thomas Jefferson Gold Dollar features a portrait of the president on the obverse with the design credited to Charles E. Barber. A left facing portrait of Jefferson appears with surrounding inscription “United States of America”. This represented the first time he was depicted on a legal tender U.S. coin.
