 I would start by giving the coin a bath in pure acetone over night to see if any of that gunk will come off. That way we may be able to see the coin and any errors it may have.

The whole back of this coin is an error and it's not gunk on the coin,if enlarged one can see that the dark places are spaces between what seems to be,or reminds me of,over stamping of another pattern making the back of the coin one big error. This isn't some glue on a coin or an error that one can barely tell is there, please enlarge your screen and view the picture, thanks

The blackish stuff is a substance "on" the coin,not a mint error. I did enlarge your photo, but it is not very clear,but I still say it is not an error.Might by paint or a black sharpie marker etc. John1

Hard to see from the pictures, but is the area where the black stuff is recessed? Looks like it might be, could be from some kind of corrosion, acid, or chemical reaction.

Whatever is on there was not on there when the coin was minted. It is not an error, but would be classed as damage.

Again the darker parts of the coin are cracks/crevices under the wording of the coin,not on top of the coin, which happened pre strike,I've seen or know of two others that were struck over foreign coins and don't know if this is the case or it was struck over a sub par planchet, again thanks for the comments

The "black" you're describing only seems to be on the low points of the reverse - nothing that sticks up off the face has any black on it. This is suggests that it has worn off the flat fields and the high points of the obverse.
Cents from that era had a problem with lamination errors and I wonder if that doesn't account for some of the crevices that appear on the reverse.
Something black covers the reverse and then wears off with the highest spots coming off first.
In any event, it can't be an overstruck coin, foreign or domestic, since the obverse has no indications of any pre-existing design.
If it had been a coin that was previously struck and then somehow made it back into the hopper to be fed into the press a second time one would see some evidence on both sides of the coin.

Please crop your photos (they will appear larger as well). The black spots on your coin pure and simple is damage. As others have stated, your coin did not leave the mint looking like this. No error was committed on your coin, sorry. No "over stamping" or big mystery with your coin. Nothing in the minting process could result in the gunk on your coin. And yes, it is ON your coin. Just because it's still there after soaking means nothing. Your cent has post mint damage, no error, no premium. I'm sorry it's not the news you want to hear. If you still won't believe us, you should send your coin into a grading service for authentication of your special "error". Be sure to show us the label when it comes back. Bonne chance.

Quote: Looks like it might be, could be from some kind of corrosion, acid, or chemical reaction. I agree 100%. A caustic substance (Acid, for example) that got on the reverse in a random pattern would eat away the surface of the copper to expose the "world" below the surface. The short lines in the recessed areas are part of the metallic composition and are left behind as the different metals dissolve at different rates, not part of a design from a die or striking error. PMD can cause some interesting damage and you found one of them.
