1980 Lincoln Memorial Cent - Never Seen Anything Like This!

Would not acid and the wire brush theories not convey the marks to the rim, also?
From the pics, I do not see any, and would that not mean that they were conveyed to the palnchet after the coin had been thru the upsetting machine? If that is plausible, then the marks would seem to have to have been applied by the die as Mr. Neff suggested.

Hi, Coop. What are your thoughts on the lack of rim distortion? The coin in your post from Coppercoin's site shows changes on the rim where heat was probably applied. The surface marks on the coin in question has markings right up to the edge of the rim but nothing on the rim proper as far as I can see. The marking on the coins do seem very similar, though.

Thx for your thoughts, Jim

Jim: The image on coppercoins.com was one from an auction on ebay. I saved the image for educational use as it would have disappeared shortly on that venue. What ever type/method of heating on that image may have cause that distortion on the lower part of the obverse. Over heating or experimenting may have caused the damage Some people win races, others crash. Depending on skill, equipment and experience. It one new how to work with the tools of their trade they would have a better chance of accomplishing a task than one trying it for the first time. Some feel is was done with a wire brush, others with heat, but all agree that it was not done at the mint. It was post mint damage. I've never tried to re-create the experiment and won't because it would just damage something I enjoy. Bad enough finding coins with road rash on them when going through circulated Cents.

Chuck: On your coin there appears to a collar issue or a holder was used to work on the coin. Probably one I would save for educational purposes to show others. But you always have a copper cent that is worth at least melt. Thanks for sharing it and your nice emails.

Thanks again to all for the great feed-back!
I'll keep this is the NON- file 13 drawer for the time being. (LOL)

Not orange peel. OP from die wear especially when heavy has a radial patter extending outward from the center of the coin. This coin does not have that radial pattern.

I've seen something similar when reverse electrolysis was used to try and remove corrosion from a coin.

The Consensus is acid bathed- Mr. John Wexler also agreed on that's what happened with this coin- Post Mint. (Thanks Coop for forwarding this on to him for his expertise).

However, one question that BJ NEFF asked earlier and I would also like to know, still has not been answered by anyone who agreed that this was not a late Die Deterioration Mint error-

"How did the doubling get on this coin" if not by Die Deterioration.


There is definitely extra columns in Columns 11,12 and outside of 12 on the Reverse and also there is faint doubling of letters on the Reverse (last S in states and around the CEN of Cents

Something else I just noticed on this coin- all the letters on the Reverse of the coin "United States Of America"- every letter is bold except the first S in states - its flat- indication of struck thru grease?
How did acid do that, UNLESS this coin had doubling etc on it and was acid dipped with the doubling and struck thru grease error already on the coin.

Which would beg the question- Why go out of your way to change the finish on the coin and destroy a coin with doubling on it?

IF that's what happened- acid dipped ,post mint, but with doubling on the columns etc PRIOR to the acid treatment- What's the status of the coin then- real or fake?

Here are some more pictures.

Thanks Bill:

Question,

Is there a way to distinquish true doubling versus acid created doubling under a scope and if so- what should I be looking for?

A co-worker has one and has offered to let me see the coin with it.
