Coins continued to be made of the same materials as before in many countries - alloys of copper, nickel and silver. Some countries began to mint coins of zinc (notably Germany) and aluminum, to save on the traditional materials, which were valuable for munitions of war.
The US government was concerned about shortages of copper and nickel, which are very useful for war materials. The US made cents of steel in 1943, and five-cent pieces ("nickels") of silver. The silver "war nickels" had a large "S" above the dome of the Jefferson Memorial on the reverse.
