Corrosion, not a good thing!!!!
Copper acetates ranging in color from green to blue. Neutral verdigris is Cu(CH3COO)2· H2O, and basic verdigris contains more Cu(OH)2 and H2O.
In layman's terms, it's copper corrosion.
<< <i>Corrosion, not a good thing!!!!
The black stuff is also corrosion, which is not a good thing.
Ditto for red raised stuff on copper, which is another type of copper corrosion - not a good thing
And if you see black surfaces on a copper-nickel coin (nickel, nickel three cent, copper nickel flyer and Indian cents and clod coinage) THAT'S corrosion, which is not a good thing.
Corroded early copper is not the worst thing in the world. True, most of it can't be slabbed by PCGS or NGC, but it's not worthless. AND if your budget is not large, it might be all that you can afford. Clean, smooth brown copper is hard to find in this market because much it resides in the happy homes of dedicated collectors who only sell when they die or get old.
The seller of this lot has described the coin accurately. VF sharpnes, porous.
Is it worth $212.50? I don't think so, but that's my opinion, and I'm an old timer who collected when porous coppers were viewed as "culls." To be frank I don't handle a lot of early copper, but when I do it's usually nice, and I get pretty big dollars for it.
Now if it was $2.99 it might be another story.

What are those things down there by the ribbons?
Even with the rough surfaces the buyer may have gotten something of a cherry. The coin is a S-239 R-3, but that variety almost always comes with a heavy die crack down through the R in LIBERTY and out into the field infront of Liberty's face and ending at the rim at 3:00. This one doesn't have the crack.
