It turns out that the solid copper U.S. cent was minted from 1793 to 1837. After that, it was "mostly" copper, and the other metals included in the alloy varied a bit from time to time. It was in 1982 that the big change occurred and the copper content of the cent was cut to the 2.5% copper used in the plating. Hey, why not surf on over to the Wikipedia post on the U.S. cent and look at the handy table showing what was in the penny at different times in history? Oh, and you'll need a link. We've got one for you, and you'll find it below.

A mixture of water, vinegar, and bleach is corrosive to most metals. If pennies are placed in it, the copper will oxidize.

If you leave the pennies in the mixture too long, holes may start to form in them.
