Exactly. I think they're made of zinc and copper coating.

"The composition was pure copper from 1793 to 1837.
From 1837 to 1857, the cent was made of bronze (95 percent copper, and five percent tin and zinc).
From 1857, the cent was 88 percent copper and 12 percent nickel, giving the coin a whitish appearance.
The cent was again bronze (95 percent copper, and five percent tin and zinc) from 1864 to 1962.
(Note: In 1943, the coin's composition was changed to zinc-coated steel. This change was only for the year 1943 and was due to the critical use of copper for the war effort. However, a limited number of copper pennies were minted that year. You can read more about the rare, collectible 1943 copper penny in "What's So Special about the 1943 Copper Penny.")
In 1962, the cent's tin content, which was quite small, was removed. That made the metal composition of the cent 95 percent copper and 5 percent zinc.
The alloy remained 95 percent copper and 5 percent zinc until 1982, when the composition was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc). Cents of both compositions appeared in that year."

I just lapped a 1981 Penny. Copper all the way down passed lincolns head.

ok nevermind. i just lapped 1 penny really good. goign to put on bottom. and i made an epoxy/as5 compound to bind them together. i used GC Electronics Super Glue 2 Part Epoxy. Mixed that then i mixed in the AS5 into it to make it thermal. i am going to let it dry overnight. i stacked up 4 pennies in a straight column. i am going to do some more when i find more pre 1982 pennies.

Taken from the air filter/freshener article.
'everyone knows that bsods are caused by your ram farting because they have eaten too much dirt. So increase system stability by making things smell better in your computer! '

This caused a chunk of carrot to go down my throat in a most unpleasant way.

It's illegal to deface all US money, coins and bills. It used to only be bills, but someone took a ton of pre-1082 pennies and melted them for re-sell as copper.
