This was a time when global communities were working together for a unified effort. Shared hardship was common, and for a war this big-- the metal, nickel, was in great demand. For the US Mint, this became a problem. For the first time in history, a nickel was minted with .350 or 35 percent silver metal content. Beginning in 1942 Jefferson Nickels were the first and only silver nickels in history.
All US nickels, except for war nickels made during WWII, are made  of an alloy of 25% nickel and 75% copper.    War nickels were struck from late 1942 to 1945. They â¦contained an  alloy of 56% copper, 35% silver, and 9% manganese because nickel  metal was needed for the war effort. These coins are distinguished  by a large mint mark letter over the dome of Monticello on the  back. Internet rumors to the contrary, these are the only US  nickels that ever contained silver.
