1986 D Lincoln Zinc Plating Missing

Adding zinc back over the copper makes alot of sense!

I agree if this is legitimate it is a one of a kind and awesome coin! But that does sound a little too good to be true.

The line would not be straight as the Liquid (acid?) would splash thus the WAVES and difference in color. I think if it was missing the copper layer the color would be even.

I like this post LOL.

For those who are for artificial de-plating the CPZ. Can you name something which dissolve the Cu without attack very strong the Zn? NO you can not. Cu it is a very resistant metal to all kind of acids, bases, etc. The HCl will solute the Cu but will eat fast the zinc. Then which solution will let the surface smooth as come after polish? And also if was submersed in a kind of solute, why the stairs do not show some Cu residues or trace of an attack. Nitric acid, sulfuric acid must be heat and will solute first the Zn.

I give a solution for de-plating by reverse electro-plating, but this solution will be apply to all the coin and impossible just partial. Here what will happened:



So is not possible without attack the Zn.

In the processes of plating, if for one reason or other the Cu anions flow will pass to fast will deposit on the anode and cathode and the plating is stop. If the flow will be to slow the same effect will be. So if a coin start to be plated and the electrical differential change creating high or to low flow, the part of the coin will be plated and the other part no.

I stay with my first statement: this coin it is legitim.

Hope some more explanations will come.

Just post mint damage .

I see nothing about this error that would cause me to question its authenticity.

For my own curiosity, is this a coin that you would have graded because of the seemingly rare error?

Likely not worth it considering the fees associated with grading versus selling value potential. Although PCGS truview photos of this coin would be fun to look at.
