2008P with deep furrow.

[MorgansRmine]

Hard to make this show as a furrow. In the pictures it appears as being raised.



Two questions on this. There appears to be no breaks in the copper plating. Is the copper plating on the coin thick enough to stretch this much if the coin was struck through scrap?

Next. If this damage was on the zinc blank or planchet prior to the copper plating being applied, is there enough striking pressure to cause this void to be filled? When you consider the size of Lincolns profile, there has to be quite a bit of metal movement during the striking process.

Can't tell much from the small shots. A full-face view would give more info, to work with.

Yes a full shot might help.

I don't think it was a planchet defect. Unless the full shot shows something else I doubt it was PM damage. Sometimes the copper can smear with PM damage but on this one from the pic I'm thinking it isn't damage, it was probably struck through something.

Here's a pic showing more of the coin. I'm convinced this is a strike through, but don't understand how the copper layer is not split as I've seen on much smaller strike throughs.

[Dick]

With the larger picture, my guess would be damage to the planchet, or even prior. you can see the undulating form in the bottom of the gouge. I believe it was plated that way. Now the fgorce of the strike would cause metal flow, but i don't see any indication. Of course, I'm not that experienced to give an educated guess. It doesn't look like the typical contact mark. It is not a fragmentation, indentation, as far as I can see. I took it to huge size, and still no sure answer. Struck-thru, or planchet damage, is the best I can think of.

After seeing the full pic I'm not sure.
It sort of looks like a roll crimper mark, it's in the right location for it.

If you see any slightly raised area along the edge of it then it probably is a mark from a crimper.

If there is no raised metal pushed up along the edge of it then I'd think struck through.

[Dick]

I hadn't considered the crimper damage, but it is very likely a, or the cause. I would expect to see some zinc, peering thru the damaged area. I don't think it happens every time, so antything is likely.

It is a strike through. Most planchet damage does not survive the striking process because of cold metal flow, unles it is a majoe defect.

A matter of semantics, but might as well be correct, eh? It's "struck-through" - not "strike through". The coin was struck...past tense. It isn't still striking.

This is not a crimper mark. It's not circular (exactly) and doesn't show any of the dug trench scrape marks common with a roll crimper. Furthermore, there are no marks anywhere else on the coin. VERY odd for a crimper.

This is a struck-through, probably metal scrap. It's actually worth a premium because the struck-through area is easily large enough to see from at least arm's length. Very nice!
