Franklin Noll talked about the history of United States currency. He showed various artifacts in the Historical Resource Center of the Bureau of Engraving and Printing to tell the story of American paper money, which was introduced nationally as “greenbacks” during the Civil War as a means to pay for the expenses related to the conflict. Photographs and clips from a Bureau of Engraving and Printing video and a 1933 Universal newsreel were also shown in the background.
