Here is an example of a 1991D Lincoln Cent...

How did the whole rim get so wide?

I was a kid when zinc cents came out, I used to achieve this effect by laying one on a hot wood stove. If you left the penny too long, it would completely liquefy. Zinc has a much lower melting point than the copper shell, so it was similar to the chocolate melting inside the shell of an M&M. I think heat may have been the cause of this one. I know there's no sign of it on Lincoln's cheek, but with the rim being the highest point, it would be affected first. I've thought about this since the post went up and am quite familiar with the ex-aluminum encased cents, but heat is my call on this one.
