CaptainFwiffo Pillar of the Community United States 4132 Posts	Posted 07/03/2011 12:46 am I almost passed over this nickel, figuring it was just PMD, but the smoothed out area has the same gloss as the fields and other parts of the devices, and there's no other evidence of gross damage beyond normal circulation nicks and scrapes. Could it be a heavily Grease Filled Die? The reverse is unremarkable. Report this Post to the Staff

Yokozuna Pillar of the Community United States 4618 Posts	Posted 07/03/2011 03:31 am I had a 1983-P Nickel that I thought was an adjustment strike, because it was weak across both sides. When I put it on ebay, an expert saw it and told me it could have been a planchet that wasn't treated properly and was too hard, not an adjustment strike. I added the information to the description and it went NUTS and sold for $45. You can check what the one I sold looked like here: https://goccf.com/t/89131 I missed that the reverse was okay when I posted the above info. Sorry about that. I was hoping it would be the same as the one I sold and make you a little money ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!! Edited by Yokozuna 07/03/2011 03:40 am Report this Post to the Staff
CaptainFwiffo Pillar of the Community United States 4132 Posts	Posted 07/03/2011 04:03 am It does look a little like your coin although mine has more missing on the obverse and less on the reverse. Now that I look at it again, the reverse is kinda weak - weaker than most 1990 era coins anyhow. Hmmm... Report this Post to the Staff
mikediamond Pillar of the Community United States 2737 Posts	Posted 07/03/2011 11:19 am It's an interesting specimen. Centralized design weakness can arise from several causes: 1) grease (uncommon smack dab in the center and nowhere else), 2) a poorly-annealed planchet or one that was abnormally hard for other reasons, 3) a weak strike (but this is usually accompanied by weakness elsewhere, or 4) die deformation with loss of fine details (a.k.a., a die subsidence error or a soft die error). I'd like to examine it up close, and possibly write it up for Coin World. If you're interested in pursuing this, contact me at mdia1@aol.com. -- Mike Diamond Error coin writer and researcher.

CaptainFwiffo Pillar of the Community United States 4132 Posts	Posted 07/04/2011 4:15 pm Just an update - I borrowed a scale; it's the same weight as another random circulated 1990-P nickel within 1/100th of a gram. Report this Post to the Staff
mikediamond Pillar of the Community United States 2737 Posts	Posted 07/04/2011 4:21 pm In your second photo it looks like Jefferson's cheek and jaw are slightly swollen just behind the mouth and chin, respectively. Is this the case when compared to your normal 1990-P nickel? Error coin writer and researcher. Report this Post to the Staff
CaptainFwiffo Pillar of the Community United States 4132 Posts	Posted 07/04/2011 5:04 pm I see what you're getting at... TJ does look a little "jowly" in the picture. Comparing it to the regular nickel side-by-side in the same light they don't look very different in that area. There is a kind of jowl/ridge present there, but it's on both coins. I am working with a cheap magnifier and not a microscope or anything, but I don't see any sort of wrinkling or anything that looks squished. I'll see if I can take a picture of the area.

CaptainFwiffo Pillar of the Community United States 4132 Posts	Posted 07/04/2011 11:48 pm Alright, I'm working with a pretty low-tech camera setup, but here are two pictures. The first is a "normal" circulated 1990-P nickel, the second is my flat one. I wasn't able to get the exact same angle and light and everything, but I tried to get as close as possible. I don't know if I can draw a conclusion. Report this Post to the Staff
mikediamond Pillar of the Community United States 2737 Posts	Posted 07/05/2011 08:47 am Looks about the same to me. Error coin writer and researcher. Report this Post to the Staff
mikediamond Pillar of the Community United States 2737 Posts	Posted 07/15/2011 6:24 pm Close inspection revealed that the coin was vandalized outside the Mint. The affected area is unnaturally flat and is covered by microscopic scratches. Pity. Error coin writer and researcher. Report this Post to the Staff
CaptainFwiffo Pillar of the Community United States 4132 Posts	Posted 07/15/2011 9:32 pm Ah, bummer. I figured that's what it was, but the glossy surface gave me pause. Thanks so much for looking at it! Report this Post to the Staff
