The U.S. Penny

So i know the penny, since 1982, is actually,97.6% zinc and 2.4% copper, that much i got from Wiki, and i've heard that if you put a penny in extremely concentrated hydrochloric acid, the inside becomes hollow, because of something the HCL does to the zinc. chemistry, not my strong point.

I don't want to put this into something i'm working on if i don't understand it. I don't need real specific details, but a basic overview of what is happening would be good. My character is into counterfeiting, and he's going to start reminising, as he's gotten himself into trouble, about how when he was young and messing around with pennies it was all so much simpler, and i want to sound as if i sort of know what i'm talking about. thanks so much for any help.
