Released on August 5, 1996, this commemorative coin honors the 150th Anniversary of the Smithsonian.
Public Law 104-96 defined how the surcharges received by the Smithsonian Institution were to be directed:
Commemorative coin programs are created by acts of Congress to honor a person, place, or event. Surcharges from the sales of these coins help fund a variety of organizations and projects that benefit the public. Commemorative coins are only available from the United States Mint for a limited time, as specified by public law.
The obverse design on the coin features a classical bust of James Smithson with the double date, 1846-1996.
The reverse of the coin features a design of the Smithsonian's sunburst logo and the word "Smithsonian". The design elements of the foreground of the coin are raised and frosted, and the sunburst on this version of the coin is incused and highly polished with a frosted background.
