    I have an answer for you but must first ask, is paint considered a chemical?

    Not black but a tool scribe should do very well.

    Ive got some nasty copper sulfate(sulfate/sulfide I get em confused) I could give ya....I know it marks up/eats iron quite fast, but not sure about nickel.

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

    Run them through Washington. That will turn them red but they may be nickels before you get them home.

    I'm sure there are chemicals that will turn most anything black.

    I know catsup takes black off of a coin.

    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.

    I've gotten back a box with about 25-30% of my coins.

    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.

    A medal stamp: Been There. Done That. hammered into each half dollar would work.
    Now... if only to locate a blacksmith who could do the medal work for that stamp. . .

    Trun a can over of air in a can and speay it on the coin. It will make a black mark on the coin. Well it works on Silver may not work on clad. image

    yeah, I'd get some silver back mixed in, but not a lot.

    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? image
    I decided to change calling the bathroom the John and renamed it the Jim. I feel so much better saying I went to the Jim this morning.

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

    You'd be able to do this using liver of sulfur and wiping some on the chemical on the copper edge. This blackens chemically but I don't think it works on the clad surface.

    I'm pretty sure that clorox bleach will turn even clad coins black. Will undoubtedly do it to silver. Would be easy to test...
  • Nic-a-date made for nickels to bring ou the worn out dates turns silver black. Not sure about clad.
  • There is a chemical agent that stained-glass / art-glass professionals use to turn solder joints from silver to black. I believe the stuff is called "patina" (not sure of the actual chemical name or brand name), but it comes in small bottles, and is applied to solder useing a little paint brush. You can buy it as any art-glass store.

    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."
