Error Plating | 1984-D What is this anomaly?

[papascoins]

It seems I've seen this before, but I can't remember what it was attributed to.
The Obverse looks like a Plating anomaly, but the Reverse shows these parallel plating blisters or something in the North, above EPU. Also on the Reverse is distorted EPU and distorted FG. I would love to hear from everyone who has seen this, or knows what this is.
Please note the plating on the obverse which has severe parallel plating 'lines', but there is a quadrangle area around the date, which is smooth, (without the plating lines). Also, check out what's going on with the rim, (most noticeable in the South on the Reverse).
Thank you in advance for looking or commenting.

I think the obverse lines going NE-SW are roller striations or lines from when the metal blank was formed. There are similar lines going in the same direction on Lincoln's bust.
The "traingle" may or may not be a plating blister. I'm not sure how to confirm if it's some type of die damage (unless poking it with a toothpick "deflates" it, then you know it's the blister.)

The wavy lines on the reverse may be die deterioration since it seems to be a later die state coin. (Those are definitely not roller striations.)

Thanks Pete. I forgot about Die Deterioration. That would explain the distorted EPU and the FG. I'm thinking now, though what you say that the wavy lines on the Reverse are Die Deterioration, that they are some sort of plating issue.
Any thoughts about the 'rim marks' in the SW and SE on the Reverse? Also a small Rim defect noticeable to the North on the Obverse?
Thanks again!

I'm not as sharp as Cliff but I'll give it a try. The majority of what I see are plating issues, obverse and reverse, for whatever reason, and what I see at the base of the reverse is too. I would need a closeup of what's going on at the rim on the obverse to take a stab at that. The area at the left of the date is odd, almost don't want to write it off as a plating issue but it may be. The hard, straight line on the right of the anomaly made me look at clashes, it kind of looks like a bay.

Thanks Pete.... Any thoughts about the 'rim marks' in the SW and SE on the Reverse? Also a small Rim defect noticeable to the North on the Obverse?
Thanks again!

Rim marks on the SW & SE? Are you referring to the rough texture to the rim from about K7 to K4?
I would guess that is just some unevenness to the zinc blank that wasn't smoothed out by the upturning process for the proto-rim. Since the copper plating goes on at a thin uniform thickness, any anomalies on the blank tend to show through.

Any chance this coin is a little under weight?

Au contraire my "tacky" friend.



You have a very sharp eye and willingness to put yourself out there with some astute observations. I always like seeing what you have noticed on a thread. You put yourself out there and 99% of the time you are on target.

The red plastic one in the middle would be me!

What I like about both of us and those that comment is the ability to open ourselves up to learning.
Thanks to everyone that likes to learn, for being there with me.
