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.
They were most likely made by accident when copper blanks remained in the press as production began on the new steel pennies. In 2008, Steve Contursi sold a 1943-S authenticated copper wheat penny for more than $100,000 to a private collector. Contursi had bought the coin only a week earlier for about $72,000. Nice profit. How to spot it: The easiest way to determine if your 1943 cent is copper (and valuable) is to test it with a magnet. If it sticks to the magnet, it is a steel penny, and not valuable (but still pretty nifty).
