This is a copper cent but it isn't coated in zinc because that isn't how the production process works.

The company that produces the copper-plated zinc planchet for the mint (formerly known as Jarden Zinc) doesn't plate the coins with zinc.
You are seeing staining or toning on column #3, not zinc. They start with a zinc core and add the copper plating.

You have a 1982P large date copper cent with a few carbon spots.

@1943copper why ask us for our opinions if your response to everyone is going to be "yes, but I still think this is what I say it is."? If you're so convinced, send it off to a third party grader for attribution and don't blame us when you waste $50 certifying that it's just a regular copper Lincoln Cent in roughly AU condition.

Seriously consider submitting it to a third party grading service for attribution--a reputable one--or take it in to an equally reputable coin shop in the greater Orlando area. Let us know what develops.

Why? It is a normal coin. By spend big bucks to just get a graded coin with a lower grade. The spot on the top is showing the same color as the nearest carbon spot.

Thank you every on for your comments. I do really appreciate them. Any information is helpful, even opinions are helpful. Yes I know I am stuck on the issue that it could be a copper penny with zinc, and then copper plated.

Petespockets55, If this penny weights in at 3.07g it is considered a copper coin, not the 2.5g zinc core type.

SamCoin, Respectfully, I wouldn't blame anyone, as I don't doubt this would be very odd to have a copper coin plated in zinc and then plated in copper. :) They have been found in other years, just not this one that I am aware of.

ijn1944, will do. :)

coop, I really do appreciate your opinion and don't mean to waste your time. I did visit a local coin shop today, hoping to get a definitive answer. None found, just the suggestion to get it graded. I plan to visit another shop later this week for a second opinion. Thank you everyone for your assistance. I really do wish I had a better camera. Any suggestions would be appreciated. Respectfully

That is correct, this is a "copper" cent, but you missed the point.

Zinc is not used to plate any copper Lincoln cents and both copper and zinc planchets are produced at different facilities, so a mixup in the production process isn't possible.

And as far as I know, copper plating can't "chip" since it is chemically bonded to the surface of the zinc (with zinc planchets).

I am by no means anything more than a hobbyist, but the grading services usually need some letter from an accepted numismatic expert indicating what error is present (lots of time and $ to verify).
So I don't believe a grading service will give this more than a cursory glance if you send it in for the reasons given by many people here, but they will gladly accept your $.

The bottom line is, what you claim this coin to be is impossible. It cannot, and won't happen.

This coin is worth a little less than 2 cents, as it's copper.

I am willing to bet my entire coin collection that this coin is normal, and nothing special.

Petespockets55, I took your theory into consideration, I found one of the infamous gold colored penny's that was zinc plated copper, and then heated to appear gold, the penny showing the scratches is actually a copper penny that had been treated and also showing signs of what I would call carbon spots and decided to do a scratch test to see if the gold color was completely through it down to the copper, it was not. (see picture). Not sure if this would be the same as a copper penny coated in zinc and then coated in copper, But, I would be willing to bet your chemical theory would not be true. That being said, the other picture with a zinc penny cut in half is the exact color I see on the original penny that my camera will not light and focus correctly. As I have stated many times before my camera sucks. Still haven't seen any suggestions for a good camera! Preferably USP type. If anyone has an explanation as to why the previous areas I have pointed out on this coin would have this zinc color, please comment. All comments welcome good and bad, helpful or not. Thank you. Respectfully

@1943, I have deleted your comment. Please keep the snark to a minimum here on CCF. I recognize that you have received a significant amount of feedback on your first several posts and your initial thoughts haven't been well aligned with many of the opinions here.
