Technically yes, but I was thinking of something that would not add too much thickness as to not jam up a coin counting machine.

too slow
the chemical idea is en masse.
although, if not searched for varieties, a marking pen would be nice to the rest of the world.

Why do you want to turn clad coins black?
Worry is the interest you pay on a debt you may not owe.

I assume he's coin roll hunting and wants to see if he'll get his own coins back. What he doesn't realize is that unless he's rolling through $20k or more a week, marking is pointless. >>
If he returns rolls of black coins to the bank he may no longer be welcomed at that bank. Most roll searchers are content to just mark the paper roll that the searched coins came in.

once.
then I've gotten a few boxes with "some" coins I've seen 3 or 4 times.
Since we used to live in the same area, I'm guessing he's seeing some of my marked coins. PS I also used a light blue pen once and marked the edges of some with red or black or green. Edge markings come off quickly though.
Hoard the keys.
Now... if only to locate a blacksmith who could do the medal work for that stamp. . .

however, marking also speeds re-searching them as I can just pass them over. This is especially true the 3rd and 4th time.

Must be copper sulfate since copper sulfide is insoluble in water.

Agreed.
Why would the OP consider anything else?
Better yet, why mark them at all?

Seems like a lot of work although it would be fun to use a stamp that says "COPY" on it.

I'm not sure if it'll work on clad coinage. I do know the stuff is very dangerous to handle ie gloves and a mask are required. Try googling "patina" and "stained glass."
