1953 Lincoln Is It Lamination Or Retained Cud?

Looks like a LAM to me. Haven't seen one like that before just hugging the rim like that. Good question. We'll see what the others think.

Kool find.

Coop knows these right away. I think it is a folded over Rim Fin or copper foil. Not a Cud of any kind.

Folded over Rim Fin may be a better fit. I have been going through the Error-ref website trying to find one. We had one similar to this probably a year ago and I have been trying to find it on my posts page. But would the folded fin happen before the strike like that (I am not that familiar with the chronological order of the coin making process)

Interesting! like to see what Coop has to say!

Does not seem to be a tiny burr, but my thinking is was if a fin was caused during the blanking process and rolled over the field during the upset process a.k.a rolling fold as it appears attached to the rim and struck into the coin, not folded after.

Could be a LAM or struck through scrap. But seems to be attached to the edge pretty good and the way it feathers out in both directions to the coins edge makes me think Rim Fin before strike. Thanks, Doug.

It was struck through a piece of scrap debris. (possible a lamination that peeled off another coin) If it were a blanking bur, it would probably fall off and leave an incuse area. But this look like something was in the ways of the strike and was wrapped over the edge of the coin. It would be interesting to see the edge of the coin on that area.

Even in the first image, it's obvious that this is an additional layer of metal that was folded back onto the surface pre-strike or mid-strike. I don't see any evidence to call this a lamination error or struck-through.

But, as always, .
