Don't judge a coin by its cover ;-]
I'm pretty sure it's zinc coated with a very thin layer of copper. Just to
make sure, I grabbed a penny off my desk and gouged it with an X-Acto knife
to expose the inner metal. It's a silvery-colored metal. Can't tell from
looks alone whether it's zinc or not, but it certainly isn't copper. (Zinc
sounds right, from memory)
