nickels were made with copper after 1945 and are worth 5 cents melt value right now. Pre-1945 nickels are worth almost $2 in silver melt value. Pennies were made with copper until 1982. Copper pennies are worth twice face value right now, which isn't a lot unless you have a lot.i didn't even know today's quarters and dimes weren't silver
what are they? and when did it change?
