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.
Best Answer: The first year for the 95% copper cent was 1864. The only year between 1864 and 1982 where it wasn't copper was 1943, when it was made out of steel (the copper was considered a vital war material). From 1857 through early 1864, the cent was made out of 88% copper and 12% nickel. Before that, it was essentially pure copper (there were often impurities, depending on where they got it from). For Canadian cents, the last year for the bronze cents was 1996.
