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.
If your 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. Pennies made after 1983 weigh 2.5 grams. One pound of pennies weigh 453.6 grams. It would take 181.4 pennies to equal one pound.Pennies made from 1959 to 1982 weigh 3.11 grams so it would take 145.7 pennies from this era to make a pound. BTW: There are 50 pennies in a roll of pennies, so the entire roll would weigh a little over 4 ounces.f your penny has a date before 1982, it is made of 95% copper.
