It didn't roll down a hill!
Back in those days when your nickle got stuck, it was a general rule that you must beat on the machine
(or kick it) until either the coin returned or a Coke came out.
Pepsi made their machines out of steel so this damage wasn't as bad, but all Coke versions are aluminum and most are dented.
Remove the door liner and you will find 90% of your dents can be reversed and just pushed out by hand.
