50 Centavos Eurico Gaspar Dutra

Dutra's administration oversaw a postwar economic expansion that strained Brazil's minting capacity considerably. The aluminium bronze alloy chosen for this series was a practical response to copper supply pressures following wartime metal controls — Brazil had exported significant copper reserves to Allied manufacturing during the war, and domestic coinage had to accommodate what remained.

The series ran eight years, an unusually long production window that reflects both the coin's successful wear resistance in tropical circulation conditions and the Kubitschek government's reluctance to authorize new dies before Brasília financing consumed monetary policy attention.
