The program requires that the reverse of the dollar depict a new design every year. In order to determine which design to depict on the coins, officials from the United States Senate Committee on Indian Affairs, the Native American Caucus and the National Congress of American Indians, the consulting organizations for the program, appoint a liaison to the United States Mint. Between twelve and fifteen themes are selected after consultation with the National Museum of the American Indian and the Smithsonian Institution. At this point, the consulting organizations supply the Mint with written comments regarding the themes. The suggestions are then sent to the Citizens Coinage Advisory Committee, where a theme is recommended. After reviewing the recommendations and input from the contributing organizations, the selected theme is finalized, at which point designs are produced that represent the theme. Once designs are created, the consulting organizations and the National Museum of the Native American are consulted, and the designs are sent to the Citizens Coinage Advisory Committee for approval. Based on all comments and recommendations received, the Mint selects a final design that is recommended to the Secretary of the Treasury for approval.
