Looks like the finning of the rim? Still trying to figure out the finning thing.

I was thinking Cud but if you say it looks like you can peel it up I would say finning that has gotten folded over when pressed |

I think either vlds or peripheral erosion.

vlds = very late die stage, which can cause merging of the devices with the die flow (wear on the die) towards the rim. Or, peripheral erosion= erosion on the die where the field meets the rim. I'm leaning towards the latter.

Thanks for your input CoinMasters : ) I think I read about VLDS today on a reply from Coop. Ruled it out because it seemed like it was a flap of metal that had been pressed against the surface through circulation. That's a term I have not seen before - peripheral erosion; again I'm ruling that out because of the flap/peal look to it, but that's a nice term to learn  Learned three new things today :D VLDS, Finning, and peripheral erosion |

I am a man of limited knowledge but peripheral erosion looks a lot like that. When the edge of the field on the die erodes, it creates a void where the metal can "flap out". I think someone that knows for sure will hap along.

I believe this is a lamination error, somewhat typical around the outer devices on 50s/60s nickels. I've found quite a few. I think that rim finning only occurs on the outer edge when the metal flows between the collar and the die (sort of like flash on a plastic part). But perhaps the metal could flow inward towards the devices instead? One of the experts will chime in and let us know.

I felt like tweak800 said makes sense; The coin is heavily circulated. The finning got folded over, and then it would then take the shape of the letters. Similar to if you fold tinfoil around a coin and put some wear into it - the tinfoil should start taking the shape of the designs on the coin. It could still be lamination as you said, that was my original thought. I'm pretty mad that I turned in a really nice lamination pealed nickel from this same box! It was a large one and I thought I had set it aside but it may have gotten mixed in with the others. After I returned the box I couldn't find it  |

I feel it is a flattened fin. Note how it folds over the top of the devices. It is were a lamination/peel, the under material would have peeled. But I'm not seeing this on this coin.

Ahh, good call Coop. Nice tip for determining lamination, in the close up shots I should see a difference in the material below the flap. Thanks!

Any chance it's a retained struck through? John1  |

If it were struck through the devices would be fully pressed down and I'm not seeing this on this coin.

Haha, thanks again SilverStackerKid. Appreciate it : )
The good call was because there were a few suggestions as to what this was and coop cleared up the lamination thing by explaining we would see a color difference in the underside of the extra material which is not seen on this coin.
