I'm not too sure but it looks like it's just worn down and hence the worn plating shows the zinc inside. As of why it is thicker, I'm not sure.
Thats what I thought at first to, and that may be right.! however, the copper finish looks almost like it was sprayed on.. Dont know if this helps, but I weighed the coin & it is 2.4 grains lighter than normal. Also strange is the rolled metal under the date on the obverse & under the "ONE" of cent on the reverse..
I added another pic to show the strange wear..
