Scuba1 Valued Member United States 356 Posts	Posted 02/20/2021 11:14 pm I almost threw this one into the cull pile, thinking PMD myself, but loupe'd it and saw something odd. The rings on the reverse were no doubt formed pre-strike. This looks obvious to me due to nothing disturbing or distorting any of the devices as you can see. Where the darkest and largest 'ring' terminates (or begins) on the left side of the reverse on the rim at UNITED, the rim is completely intact. There is another raised ring that runs along the bottom through the shield, shield not disturbed, and continues through OF and AMERICA and beyond. There's just a lot going on with this coin that is better left to see in the pictures. I am just not sure what caused this during the creation of the planchet. Please take a look and, as always, Thank You for your replies and comments. Report this Post to the Staff

IsThisAnything Valued Member United States 440 Posts	Posted 02/20/2021 11:22 pm If I saw this, I would rule it a cup holder coin. Can you tell me more about what tells you it happened pre-strike? Report this Post to the Staff
Scuba1 Valued Member United States 356 Posts	Posted 02/20/2021 11:29 pm Hello ITA. Please look at the pictures closely. Not a cup holder coin. This was my question: What happened pre-strike? I do not know. Report this Post to the Staff

I promise you it did not leave the mint in this condition. Spend it while you can. Edited by merclover 02/20/2021 11:48 pm Report this Post to the Staff
Scuba1 Valued Member United States 356 Posts	Posted 02/20/2021 11:45 pm Quote: No doubt post mine damage w/zinc rot. I promise you it did not leave the mint in this condition I am very clear that there is zinc rot on this coin. I have been collecting Lincoln's for quite awhile. I also promise you it did not leave the mint in this condition with zinc rot as clearly shown, totally agree. I'm not sure how far you scrolled down to see all of the pictures but please explain to me the raised ring and the other incuse and raised defects on this coin that did not damage the devices. Please explain how PMD would cause this. Thank you. Edited by Scuba1 02/20/2021 11:47 pm Report this Post to the Staff
CoinHI Pillar of the Community United States 2735 Posts	Posted 02/20/2021 11:52 pm Residue or adhesive from another coin or coins stuck to it for awhile, maybe acidic and ate through in areas.

merclover Bedrock of the Community United States 10635 Posts	Posted 02/20/2021 11:59 pm PMD can occur a million different ways. Something acidic was sat on this coin (probably coffee) that ate into the surface. Zinc rot came later, and is still eating away on this poor cent. Zinc rot can cause the surface to be raised where the rot is eating away happily. If you are positive it's a mint error, send it into a TPG and slab that puppy (but slabbing won't stop the zinc rot).

I love it Merclover! I've seen a lot of Linc's and can predominately rule out PMD and the such (not saying this is a bonafide mint error.....) but I'm just not sure viewers are looking closely at the entirety of the pictures. Can anyone see the rounded raised circle at the bottom of the coin in the CLOSE UP pics? If it was eaten away by some acidic substance it would have eaten into the devices as well.

Coinfrog Bedrock of the Community United States 94367 Posts	Posted 02/21/2021 08:59 am Several possible causes, but definitely post-mint damage. Report this Post to the Staff
JimmyD Bedrock of the Community Canada 21620 Posts	Posted 02/21/2021 1:13 pm It can't be a planchet flaw and there are only certain things that can cause an error during the striking of the coin. It doesn't really matter how it happened, what is important is that it cannot be an error so therefore it is PMD. Report this Post to the Staff
ijn1944 Bedrock of the Community United States 19184 Posts	Posted 02/21/2021 1:27 pm Post strike damage--cool example at that. I'd drop it in a 2x2. I suppose one could roll the dice and submit it to a TPG. Report this Post to the Staff
Scuba1 Valued Member United States 356 Posts	Posted 02/21/2021 2:44 pm Thank you all very much for your replies. I'm not one to keep 'beating a dead horse' so to speak but I'm just not convinced this is PMD (I do value everyone's thoughtful opinions though). Not that an acetone bath will remove zinc rot, which it does have no doubt, but I may try it to see if some of the stuff on the reverse is gunk so I can maybe get a better feel for this one. The more I look at the less than spectacular pics I posted the more I can see how it definitely and absolutely appears to be PMD without having this coin in hand. I thought the very same thing myself until I took a very close look. Thanks again for your responses! Edited by Scuba1 02/21/2021 2:46 pm Report this Post to the Staff
