1793-1857 large cents : 100% copper
Small cents from 1858 to mid-1864 : 88% copper, 12% nickel
From mid-1864 to mid-1982, except for 1943 : 95% copper, 5% tin and/or zinc
1943 : steel plated with a thin layer of zinc.
Pennies from 1982 and before were all copper
1982
Pennies were never PURE copper. Those made before 1982 were 95% copper with 5% zinc (or zinc with tin in older ones).
1982
1982. before that, a penny was made up by 95% copper (Cu) and 5% zinc (Zn) and/or tin (Sn). A penny made after mid-1982 is 2.5% Cu and 97.5% Zn!
Pennies from 1982 and before were all copper
Pennies today are made of 97.5% zinc and 2.5% copper.
Pennies before 1982 were made of 95% copper, which has a higher density compared to the 97.5% zinc composition used in pennies starting in 1982. This change was made due to the increasing cost of copper.
The pre-1982 pennies are 95% copper and 5% zinc. Post-1982 cents are 97.5% zinc and 2.5% copper.
No. A penny is made out of copper-plated zinc.
Post-1982 pennies, which are primarily made of zinc with a thin copper coating, have a mass of 2.5 grams each. This change in composition was made to reduce costs, as copper prices had increased significantly. Before 1982, pennies were made mostly of copper and weighed 3.11 grams.
Cents weigh different amounts depending on their dates. Before 1982, cents weighed 3.11 grams. Cents issued after 1982 weigh 2.5 grams. Cents issued DURING 1982 could weigh either amount (is this getting complicated enough?) A pound is equivalent to 453.6 gm, So with pennies made before 1982 it would take 146 pennies to get 454.6 grams... With pennies made after 1982 it would take 182 pennies.
Pennies dated before 1982 are typically made of 95% copper, giving them a reddish-brown color and a higher weight. Pennies dated after 1982 are made of a zinc core with a thin copper plating, giving them a lighter weight and a more golden appearance.
No. Pennies made before 1982 were 95% copper, with 5% zinc.
All US pennies made before 1982 are copper, along with some made in 1982 that are copper, however, copper-coated zinc pennies were also used during that year making identification by weighing necessary.
The composition of the United States penny changed from primarily copper to primarily zinc in 1982. Pennies made before 1982 are composed of 95% copper and 5% zinc, while those made after 1982 are 97.5% zinc and 2.5% copper.
Post 1982 pennies in the United States are made of 97.5% zinc and coated with a thin layer of copper. Prior to 1982, pennies were made of 95% copper.
