The effect of WAR on US Mint Marks

  reconstruction to 1909.

  Philadelphia and not reused until 1979

The effect of WAR on US Coins

• 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.
