1942 Nickels- Silver or Nickel?

Bought $10 face in War Nicks today, after inspecting them closer at home I noticed one that looked off. 1942 without a Mint Mark above the dome. I'm guessing its not a silver?
Either way, was a great deal. The guy owned a pizzeria and gave me 2 slices and a soda on the house!
make up for that one Nick
