SamCoin, I agree. Sorry I can't find the reference. It was a graded coin and supposedly authenticated. Sorry I don't have the reference. If I find it I'll post it.

Just throwing photos won't change the reality that your coin is suffering from carbon spots. It's not unusual, nor does it make a coin valuable, in fact, it's undesirable damage. With several postings, you refuse to accept our input and keep asking for more thoughts. Well, our thoughts haven't changed. Spend it.

Just to reiterate, as others have stated... modern cents have a zinc core, plated in copper. Your cent is clearly plated in copper, therefore cannot be an unplanted zinc planchet. The spot you are seeing just looks like oxidation to me. If you are seeing any "silver spots" on that column or the rim of the coin, it may be from the zinc underneath the copper, not from any zinc on top of the copper.

Edit: this is what happens when I post too late. Overlooked the fact that was a copper at that weight. Then it's just oxidation or discoloration on that 3rd column. Would not be the exposed zinc core.

Again, impossible to be "zinc plating" from the mint, as there is no such thing.

Ty2020b, I agree 100 percent! that is my argument. This is a copper coin. As noted in the description. It weighs 3.07g. Thank you for your input.

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.
