4. May 15, 1937

   The Treasury Department picked this undeveloped serpentine bluff above Upper Market Street on 2 August 1934 because vaults could be sunk into the rock. The Office of the Supervising Architect under Gilbert Stanley Underwood designed the four-storey granite-faced building in the PWA Moderne style, massed to look forbidding, its only ornament a row of parapet medallions showing the coins to be struck inside. Clinton Construction Co. built it for about $1 million from August 1935 to March 1937; it was dedicated on 15 May 1937 and began minting coins on 1 July.
