1946 D Jefferson Nickel. Almost A Clip?

The center swirl on Reverse reminds me of coin dispenser markings; you know the old school ball park hot dog vendor thingys. Coin could have got jammed in one and enough force applied - AKA hammer to the lever - to cause some PMD by the push out arm. Thats all I got !!!

It seems to me that the perimeter of the coin was pinched after the coin left the mint. Later circulation presumably pushed up an elevation along the outside of the pinched metal on both faces. I cannot entirely rule out damage to the blank (i.e., pre-upset). However, if this were the case, I feel that the two "lips" on the edge would have been flattened down to a greater extent by both upsetting and the strike.

Thank you all for your comments and opinions.
I'll put it down as one of those maybe ( not sure).

@Coinhi.
I thought the same thing at first. But to put something braced on that side so to pinch the other side on both sides of the coin, just thought it would've caused more damage there. The rim is only pushed in a small amount on the reverse side. I'm still wondering, how did the letters get pulled away in sort of a straight line from the curvature of the rim on both sides? To move that much metal would've taken a lot of pressure. ( Even if that was possible.)

I really appreciate everyone's help, on all the questions I come up with for the coins I post.

Thanks. Rob
