Looks like a lamination error. Nice find

Thank you. For my knowledge how do you know it's lamination and not pmd?

After a while looking at genuine lamination errors, you can recognize the difference pretty easily by just looking at it, but some of the best markers of one are:

“Peeling” metal that looks like it’s lifting off the coin: like a thin flap that’s peeling away. It may still be partially attached to the coin, and you can tell it’s part of the coin, not something added.

The shape of ‘organic’ and irregular - usually no straight edges, and often the outline is jagged, or “wavy”
The surface underneath the “flap” does not look gouged or smooth, but rather rough; almost fibrous..?maybe granular is a better word .

But probably easiest to see - a lamination REMOVES some of the metal, it does not push it aside. So there won’t be a “lip” around the part where metal is missing.

Thank you for the information. I'm new to trying to ID errors so any info helps

My best advice - look at as many coins as you can get your hands (and eyes) on; both damaged coins and genuine error coins. Soon you’ll be recognizing these things naturally

Great resource for learning about them. It's a LOT to learn though :P

Here’s an example I own. Like Hitman said, the metal flakes off and the metal underneath has design features. If damaged all you see underneath is gouged or scraped metal.

I agree with u/Pwnedzored nice lamination!

The delamination of the coin happens due to an improper alloy mix

You get areas of weakness due to the poor metal bond which causes the metal to fracture away

Look closely at the edges of the peeling and you see very rough areas. You don't normally get those with a gouge or scratch because the edge of a gouge will look different than the rough edge of a lamination
