This looks bad, but is in focus. Features are shallow and the coin has holes as if it were molten and some casting bubbles popped out. I'll try to get better pics of the areas with holes. Ideas as to how or why it looks this way? ![Opinions-About-This-Odd-[1938-S]-Lincoln-Cent?](uploaded/albert/20231103_oddpenny2.jpg)

PMD for sure, maybe acid?

Here are different pics featuring the holes. I doubt acid, but am not sure. I wonder if someone tried to make a cast copy for reasons unknown? I know that casting can have blow outs and pin holes. Again, although it doesn't look it, the images are in focus. The coin really looks bad. ![Opinions-About-This-Odd-[1938-S]-Lincoln-Cent?](uploaded/albert/20231103_pennyholes1.jpg) ![Opinions-About-This-Odd-[1938-S]-Lincoln-Cent?](uploaded/albert/20231103_pennyholes0.jpg)

Albert, how does the third side (edge) look? If it was cast, there will be a sprue mark somewhere. It would have been filed down, but close examination should reveal an anomaly somewhere.
Inordinately fascinated by bits of metal with strange markings and figures

Sorry but everything about this coin is just damage. It did not leave the mint looking this way. Looks like it sat in the ocean for about 50 years.

I don't think it was intentionally applied acid. I think it is environmental damage, that was at some point cleaned off, leaving the pits and damage to the features.

..." Looks like acid."... ..."Looks like it sat in the ocean for about 50 years."... I believe that either of these effects would most likely leave a high degree of verdigris coating on the coin ... ...High heat / bubbling would have most likely changed the color on the copper surface ... ...DANG...this is a tough one... don't think a good answer has been reached yet ... ...still going with PMD, but how...

Exposure to a corrosive environment. I'd keep it as a fun curiosity.

Contaminated by salt water, being buried, acid dip , industrial solution of sort or even household cleaner any number of things damaged this coin, it has a value of one cent.

Acid, base, or other corrosive chemical. I don't think those substances would leave verdigris—in fact, many of them are cleaners in their own right.

agreed acid or other type of environmental corrosion.
