On the coinflation website it is noted "** The U.S. Mint issued two compositions of the nickel in 1942. The standard copper-nickel composition used today and the 35% silver composition listed here."
My question, being new to playing with the nickels, is how in the world do you know when you have run across a '42 silver nickel as opposed to the copper-nickel composition? Thanks and Merry Christmas!
