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.
Before 1982, the penny was made of copper which is why they, unlike most other coins, don't look silver. However, after 1982, the U.S. government realized that it was too expensive to make a pennyâmore than the penny was worth in moneyâso they decided, instead, to make it with a mixture of two different metals. Nearly ninety nine per cent of the penny is made of zinc while the other per cent (at most) is made of copper.
