Haven't a clue about this Lincoln cent. It appears to have missed the copper plating process and has the color of dull zinc. In addition the surfaces are severely pimpled like a cast copy would be but who would cast a worthless penny? The weight of this coin is 2.47 grams which seems normal. The diameter is a little larger than normal (should be 19mm and this is 19.4mm) and the coin seems a little thinner than normal too (supposed to be 1.55mm and this is 1.4mm)

People do all kinds of weird things to coins. Experiments, jewelry, boredom. I don't remember what does this though. Experts will for sure. I've seen some really informative threads on here that I have clearly forgotten, but it's PMD.

The little bumps are most likely from zinc dust that was plated over. So maybe a normal plated cent with some kind of environmental discoloration ? Others may know for sure.....

To me it looks like environmental or chemical damage, it may have spent time buried in acidic soil. The zinc surface appears to have had a chemical reaction on it rather than what is seen typically with zinc dust. Metal has a terrible reaction with soda soft drinks, perhaps this is a science experiment reject? Who knows. Bottom line is this poor cent has seen better days and now suffers from post mint damage ( PMD).

Plating bubbles + environmental damage. There's also a bit of a MAD.

At the risk of piling on, I agree with the plating bubbles/environmental damage verdict.

It's called a 'Texas Cent'.
I have a coin just like that. larger in diameter and no copper cladding. According to Coop and a few others, it turned out to be a squished cent and the cladding fell off revealing the zinc core. Even the weights between our 2 coins is very similar. only .02g difference.

I agree. It was was probably placed between to pieces of leather and then squeezed that made the coin larger, and the plating falls off. as mentioned, the zinc dust, stayed with the coin.

Interesting what people do to coins. I took another look at the edge of the coin and at the top of the upset rim on the obverse there appears to be a seam all around. It is at the top of the rim (not in the center of the edge). And the rim looks chamfered there leading me to suspect that someone bonded one surface to another and perhaps the pimples were a result of slag. Someone trying to perfect their counterfeiting skills on a worthless penny as a test?

No slag involved with zinc. The dust was plated onto the coin. When the plating were away, the zinc dust is till hanging around.
