Canadian pennies, specifically...I got this Canadian penny in circulation and it has the weirdest "chip" along the edge that makes it look like the thing is hollow, or at least fused from two separate pieces of copper. I don't know much about the minting process, and I'm sure this is a big nothing, but just thought I'd post it.
As far as I know they are not hollow, but that does not mean that someone did not mess with your coin.
I remember watching something where they removed the zink core leaving just the copper shell. Of course, on modern coinage, it would be a shell too thin to even support itself, so that's not the answer. Guy~
i dont know about canadian cents but i know (or atleest pretty sure) US cents (post-82), when the zinc core is exposed to the enviroment it corrodes at a faster rate than the copper shell leaving a hollow cavity.
You are right about that! I metal detect for a hobby and almost all clad pennies I find are rotted away!
It would not be possible to strike up a hollow coin. It would not be possible to strike up a hollow coin. If hollow after striking it would not be hollow any longer and why go to the expense of creating hollow planchets - it would not make any since.
