Thin 1942 Jefferson Nickel
Good morning. After my good fortune with the "skinny penny" I thought i would try my my luck with a thin nickel. The thin one is a 1942 (not sure if copper/nickel or silver alloy). It weighs 2.047 grams, is .044"/1.15 mm thick and .786" in diameter. Is it an error or the dreaded washing machine.
