Lincoln cents issued before 1982 were made of bronze, which is about 97% copper. The exact amount varied a little at different times depending on the alloy used. Those cents weighed 3.11 gm so that would mean each had about 3 grams of pure copper.
The rising cost of copper forced the Mint to change the cent's composition in mid-1982. New cents are struck on zinc planchets (blanks) that are then plated with a small amount of copper. Zinc is lighter than copper so new cents only weigh 2.5 gm. The plating is about 2.5% of that, so they contain only 0.0625 gm of copper.
Because the Mint changed composition in the middle of 1982, it's possible to find cents with that date made from bronze and others made from zinc. The only way to tell them apart easily is to weigh the coins.
