This bill, known as the "United States Colored Troops Congressional Gold Medal Act," authorizes the posthumous award of a Congressional Gold Medal to African Americans who served collectively with Union forces during the Civil War. The medal is intended to recognize their exceptional bravery and outstanding service to the nation. The Speaker of the House and the President pro tempore of the Senate are tasked with arranging this presentation. The Secretary of the Treasury will design and strike the gold medal with suitable emblems and inscriptions. Following its presentation, the medal will be given to the Smithsonian Institution for display and research. Congress also expresses its desire for the Smithsonian to make the medal available for display at other locations associated with the United States Colored Troops. Additionally, the bill permits the striking and sale of duplicate bronze medals to the public, with proceeds supporting the United States Mint Public Enterprise Fund.
