The coins are 95% copper from 1864 (except 1943) to 1982, from 1857 to 1864 88% copper, 1793 to 1857 100% copper.
In 1982 the US mint changed the composition of the penny from mostly copper to zinc which changed the weight form 3.11 grams to 2.5 grams and made the penny cheaper to make.
Pennies minted in this time were made of more copper than the pennies minted today. These pennies (made of 95% copper) are technically only worth the face value. However, while it is not yet legal to melt them down, they contain a higher metal value of about $0.0254 or 2.54 cents. Some of the older coins, especially those in great condition, are worth closer to 3 or 4 cents.
Beginning in mid-1982 the cent coins were changed to zinc with a thin copper coating. A silver cent would have cost over a dollar to manufacture at that time and probably nearly $2 by now!
1980-S pennies were only issued in proof sets. At a minimum, they are worth about 75 cents. The highest grade proof condition pennies are worth $4.00 and up.
U.S. coins dated before 1980 (and all pennies) that do not have a mint mark, were made in Philadelphia.
Pennies minted before 1982 are composed of 95% copper and 5% zinc.
Starting mid-year in 1982, pennies were made with a zinc core and copper plating. This would give them a 97.5% zinc content and 2.5% copper content.
1980 pennies = $19.80. $19.80 is worth almost $20.

100*19.8 = 1980%
The main difference between a 1958 penny and a 1980 penny is their composition. The 1958 penny is made of 95% copper and 5% tin and zinc, whereas the 1980 penny is made of 97.5% zinc and 2.5% copper. Additionally, the design and mint marks on the coins may be different based on the year of issue.
