The Copper Penny Is Worth More Than One Cent

Dec 10 2019It contains about 2 95 grams of copper and there are 453 59 grams in a pound   The price of copper on Dec 10 2019 was $2 75 a pound   That meant the copper in each penny was worth about 1 7 cents Thus the meltdown value of a pre-1982 penny was about 70% more than the face value
