From an Unc roll of 83P, looks like acid dropped onto coin or copper solution not mixed well. Because this probably happened at the mint does that make this an error coin? Or since the reaction has been active for almost 30 years, damaged coin?  |

Looks like it came out of a roll that was stored improperly. The damage was done after it left the mint.

For the sake of discussion, even if this did happen at the mint, there's no way to prove it because the effect is identical to something that is rather common and shows up a lot. Anything that fits this bill is not collected as an error for that very reason - nobody knows about - or - cares about what would be the 'real deal' so they don't collect them, and a large part of the value of coins rests on demand. No demand, no value.

Almost anything that happens to a coin after the moment of striking, even if it happens while the coin is still inside the Mint, is still PMD. The only exception being edge errors on the President and NA dollar coins since those inscriptions are applied post strike. |

Because it was in a solid roll of unc 83 P cents. I know that doesn't mean it was done at the mint. Could have happened at the Fed or at an armored car coin rolling service.

Did coins come from the mint in rolls back then or were there only bags?

The mint never sent out coins in rolls until they started providing rolls of Sac dollars and SELLING rolls of State Quarters in 2000 |

OK fellow coinpeople,
As a geologist I can tell you copper offen expresses itself in green color. The spot on the coin is a green as found in the copper mineral malachite. This was probably done as the copper coating was applied.
As a collector, I don't have to sell a coin to collect it. Not all coin collecting is done for profit. Comments about it not being worth anything so it's not collectable are statements a coin dealer would make. I know a different point of view......Al

This was probably done as the copper coating was applied. Nothing like that could occur during the electrochemical plating process. Your coin displays the classic signs of split plating corrosion, aka zinc rot, which is especially prevalent on the early Zincolns. Quote:

"I have this coin/error/whatever, how much is it worth?" That is the reason for the comments about value(or lack thereof) and also to definitively let you know that the coin is just damaged and only worth one cent. The vast majority of us are collectors, not dealers, but I fail to see the logic behind wanting to collect damaged coins  |

Zinc Rot. It does look like it was dipped in something, but still no error. Spend it now!!
