https://www.ebay.com/itm/365274507771Ran across this listing while buying another coin. Superficially, it looks like a collar clash because the teeth marks are approximately spaced like reeds, but I haven't read about any with drag marks into the coin face. I checked Error Ref, but it basically just has normal collar clash examples. However, it's possible that I'm searching for the wrong term because I don't know the correct term. It also seems plausible that this could be a vise job, PSD, or PMD. I don't know how a collar event could happen on both faces simultaneously. https://www.error-ref.com/?s=Collar+clashFor the record, I am not in the market for this coin. Just thought it was interesting.

I'm wondering if it's damage from the machine that seals the cellophane mint sets?
Errers and Varietys.

Hmm very interesting. That coin seems to be a real Collar Clash, no idea if it can appear on Obverse & Reverse simultaneously, the literature doesn't mention that being a possibility.  |

What I think is odd is the grooves are slanted in opposite direction until they meet in the middle then one is straight. This is on both sides, therefore I think it is damage.

Could a cellophane sealing machine do that kind of damage? A cupronickel coin is hard. I imagine that the sealing machine just uses a little heat, like a freezer vacuum sealer.
Also add to the list of possibilities that someone could have tried and failed to set the coin into a bezel.

I was looking for any tooling marks zoomed in at 400% and saw none and thought to myself "how could this be done without leaving tool marks". Oldguy's observation hit me and I came up with one roller from a knurling tool could accomplish this and would also explain the gouges. So I think this is a good candidate for PMD. https://www.mscdirect.com/product/details/78123304Edited by Seeker_101

It's gotta be PMD. The edge is dented from whatever happened. |

Could someone have tried putting it through a can-opener.

Can opener theory is very solid. Would be easy to test theory...  |

Not to split hairs, but a can opener typically has a blade on one side and a toothed gear on the other. Unless you are talking about one of those fancy ones that hug the rim and cut the sides (a.k.a. the manual can openers that I can never get to work right).
