Pennies were made mostly of copper until  mid-1982, when the composition was changed â¦to 97.5% zinc with a  plating of 2.5% copper.    The only exception was in 1943 when wartime copper shortages forced  the Mint to make pennies out of scrap steel. Bronze cents were  resumed the next year, 1944.
What's the Difference. If your Lincoln Memorial penny has a date before 1982, it is made of 95% copper. If the date is 1983 or later, it is made of 97.5% zinc and plated with a thin copper coating. For pennies dated 1982, when both copper and zinc cents were made, the safest and best way to determine their composition is to weigh them.
