The composition in 1982 was changed to an alloy of 99.2 percent zinc and 0.8 percent copper, plated by pure copper - making the total composition 97.5 percent zinc and 2.5 percent copper.
Are you sure that it's not copper? Sometimes it discolors. Or, the copper could have reacted with another chemical to leave the zinc below.
The second link is an experiment to see how much copper is in a penny. I tried earlier this summer, and it is kind of neat, but it takes a while for the zinc to react. You are left with copper that is the thickness of gold foil.
I haven't tried the third link.

United States pennies made after 1981 are made of copper-plated zinc.
