The composition was changed in the middle of the year so some 1982 cents were made of bronze while others are copper-plated zinc.
The best way to tell them apart is by weighing them. Bronze cents weigh about 3.11 gm, zinc ones weigh 2.5 gm.
Copper
US pennies (since 1982) have been made of zinc (97.5%) with a thin layer of copper (2.5%) outside.
Pennies are made of zinc and other alloys with a copper coating, pennies made before 1964(or around this year) they were made of just copper. What you see on a penny is not rust but corrosion of the copper coating.
You can tell if a penny is made out of zinc or copper by the date on the penny. If the date is before 1982 then the penny is 95% copper. Pennies dated 1983 or later are 97.5% zinc with a thin copper coating.
copper
No, pre-1982 pennies are 95% copper and post-1982 pennies are made out of mostly zinc with a thing copper coating
1982 to date are 99.2% zinc & 0.8% copper
Pre-1982 copper pennies weigh 3.11 grams. Pennies made since then are mostly zinc and weigh 2.5 grams.
The pre-1982 pennies are 95% copper and 5% zinc. Post-1982 cents are 97.5% zinc and 2.5% copper.
No, pennies do not contain gold. Modern pennies are mostly zinc with a little copper, older pennies are mostly copper with a little zinc.
U.S. cents made before mid-1982, and British pennies made before 1993, were struck in a bronze alloy that was mostly copper. Some very early cents and pennies were struck in pure copper. Modern U.S. cents are made from copper-plated zinc, and British pennies are made of copper-plated steel.
1982
pennies are made of mostly zinc but have some copper in themMoreThe composition of US cents was changed from bronze in mid-1982. The coins now have a zinc core plated with copper (rather than mixed together). Zinc makes up 97.5% of the coin by weight.
Pennies produced in 2004 were made from copper-plated zinc. Pennies with 95% copper metal have not been produced since 1982.
Pennies from 1982 and before were all copper
1982
Pre-1982 pennies are made of bronze, which is 95% copper plus 5% tin and/or zinc. Post-1982 pennies are zinc with a thin coating of copper.
