  • World War II – to save the metal nickel for tank armor “Silver” (35%) nickels were introduced in 1942 and remained until 1945. The mint mark was moved to over the dome of Monticello to denote a different coin was in circulation
  • One year later in 1943 the penny was struck with zinc plated steel planchets to save copper, but in 1944 the “steel” penny was changed back to a copper based one. These “copper” cents were made from spent ammo casings until 1947 when the pre-war composition was reintroduced.
