One of the lesser explored National Archives and Records Administration (NARA) facilities, for numismatic material, is the Denver location. John Graffeo, formerly at the American Numismatic Society, has for several monthsbeen scanning numismatic material at the NARA Denver location on behalf of Newman Portal.

John recently scanned a group of over 200 photographs taken at the Mint during the 1930s. These depict many aspects of the coining process in addition to exterior shots of the building construction that wasunderway at the time. As most of these photographs came with no context, Roger Burdette has curated the entire group and contributed useful commentary. In this photo a Denver Mint workman tends to the punching press, and onesees the familiar webbing (also called "scissel") ejected after the blanks are punched from the strip.
