Hello all, I pulled this Kennedy half roll searching a while back and was wondering if it might be an improper alloy or improperly annealed planchet? It seems to have copper partially on the outside rather than in the core. If it is an error what might it be worth?

Thanks,
-XoG

If comparing a clad coin to lets say a sandwich, then not much bread on that one. Even if it turns out to be post mint wear there was a problem with the mix long before the actual punch of that coin. I may of mentioned this once before on here a while back but we call certain effects on lets say a 95% copper cent laminations etc. but in fact the term lamination would fit a clad coin. They all are in essence laminations in themselves. So I guess you could also have a lamination error on a clad coin. A 95% copper as well as a clad coin are not plated. I never really did like that term
lamination error when referring to what we are used to seeing as far as the effects shown on a Wheat cent for example. But that would be discussion for another post topic.

I would say that the general concensus would not technically
call it a lamination error. I want to hear from others myself
on this phenom. (your coin)
I was just making a point about the term lamination error.
Most likely yours will be called either an alloy mix problem
or PMD. Regardless, I beleive the value would be minimal or
none above face. Different looking though and maybe would just keep as an example or oddity. Example, once the proper
term is finally decided on that caused your coins current state.
Rest in Peace

This is PMD. It does not look to me like it is missing any layer and the surface does not look like a delamination would look like. The coin was just damaged possibly from being buried. The outer layers are mostly copper even though they are silver in color so from what I understand damage causing a chemical reaction can cause the copper in the outer clad layer to migrate to the surface.

Exactly - it's just damage. Something coating the coin.
Rest in Peace

PMD similar to brown/purple nickels dug up by dirt-fishermen, or possibly rust that's attached itself to the coin. CLR or Limeaway might remove it.

Interesting, well thanks for the responses guys. I guess the concensus is its PMD.
