Released on August 5, 1996, this commemorative coin honored 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 an image of the first Smithsonian Institution building, known as the "Castle"; laurel leaves, and a dual date.
The reverse of the coin features a design of an allegorical figure carrying the torch of knowledge and sitting atop the world. This figure holds a scroll inscribed with the words, "art, history and science," and "For the increase and diffusion of knowledge."
