I have a few coins with various dots like this. I wont use the red 24 since you think that's not the same thing (it is) but here is a non-white one.
I am not sure what terminology you were looking for. There was a contaminant adhered to the surface that either accelerated or inhibited the thickening of the patina. It might also still be adhered to the surface. There is no specific numismatic word for this phenomenon, so I resorted to a scientific one. You obviously seem to have no idea what you are talking about, so you have no right to comment on other people’s knowledge. But since you are so sure of yourself, please enlighten the world as to what terminology should be used.
I've always called those things carbons spots. I've always assumed they come from drops of spittle when open mouthed cretins examine coins. If they are particularly annoying and ill - informed they will also deposit fingerprints - usually after or while eating potato chips.
Those are just the result of a contaminant affecting the coin, as TypeCoin971793 said. I don't know any numismatic term for it.
I am sorry too as it was not fair to post such an incomplete thread. But since it brought into question my intelligence, I will explain. This was part of a bigger discussion that I extracted away from the toning premium thread so at to not muddy that thread with Off Topic. For years now, nearly a decade, Lehigh has been tormenting me about my 1921 Peace dollar which has lavender and peach toning, unusual for the series, and especially for the year. He has thrown his high stakes poker game in my face to infer my poverty which itself infers not knowing about luxurious things like coins and such. He has even gone as far as to threaten me with mafia ties from his days working as a casino executive. I have been merely stating that the 2 marks on Lady Peace's neck are coincidently paired off and in a prominent spot on her neck, raising in the human psyche our natural desire for conspiracy theories. In short He claims the coin was most likely zapped with electrodes and artificially toned in a lab by a scientist. But I think its just 2 common pieces of...schmutz. So I was showing him other such examples as he requested in that other thread. This thread was really just meant for him to read (hence the "For Lehigh" in the title). But I am not mad at your response and I totally understand how that looked like I as calling you a name.
I find it a little hard to believe that those would be electrode spots. Surely anyone with enough knowledge to set up electronic toning would have the common sense to put the contacts on the coin's rim...?
