I wonder if it was ever a coin to begin with. I've found white-metal cast replicas of modern coins that looked like this. Often they have traces of a loop mounted on the top, from where they were no doubt once attached to a charm bracelet.
Sure, this could be a real (but really messed-up) 1973 Canadian cent, but I wonder.

Can you get an accurate weight of it ?
I agree with it having been submerged in a acidic liquid.
