What Year is the Penny made of Copper. The U.S. penny, or one-cent, was made of copper mid-way 1982 and older. Since the switch over occurred during the year 1982, the only safe way to know if your penny is copper is if the date is 1981 or older. The copper penny is 95% copper and there are approximately 147 copper pennies per pound.
The oldest metal object found in the Middle East consists of copper (it was a tiny awl dating back as far as 5100 B.C.). The U.S. penny was originally made of pure copper (nowadays, it is 97.5 percent zinc with a thin copper skin). Copper ranks as third-most-consumed industrial metal in the world, after iron and aluminum, according to the U.S. Geological Survey. About three-quarters of that copper goes to make electrical wires, telecommunication cables and electronics.
