1983-D Die Crack or Zinc Rot??

09-06-2014, 07:02 PM

Well I guess the title says it. I can't decide if the raised line I see on these two coins is a die crack or a line of zinc rot.

On coin #1 the line is on the obverse side of the coin starting just to the left of the L in Liberty and travels in a straight line to between the I and N in IN. A smaller second line runs parallel to the first one just to the south west of the I in IN. The line is not a consistent thickness but even in the low areas under my 30x it can be faintly seen. The picture does not do it justice but best I could do with my IPhone.

I also have a second coin #2 with the exact same kind of line on the reverse side running from near the NW corner of the Memorial, through the PL in PLURIBUS up through the second S in STATES and stops just shy of the rim. It is a lot fainter.

After reading several articles and what I learned yesterday about zinc rot I can not decide which these lines are. Any thoughts you all have would be greatly appreciated.

Thanks,
DKheart

Neither. They are linear plating bubbles. They generally form when the plating doesn't adhere to the planchets surface.

I agree with Gilbert. These are both cases of linear blistered plating

All opinions expressed are not necessarily shared by willbrooks or his affiliates. Taking them may result in serious side effects. Results may vary. Offer not valid in New Jersey.
