I'm looking at this coin and see 'stuff' on the surfaces that the seller describes as dark verdigris. I've been through the verdigris 101 course on this forum but it was green not black. In my effort to become smarter I'm asking for help. Do you think this can this be removed with acetone, xylene, and/or verdicare?   Member ANA and EAC "You got to lose to know how to win".

Do your research before trying this, but a quick google search turns up that an acetone bath may help you here. PLEASE search this. I don't want to be the one responsible for ruining such a pretty large cent.

100% pure acetone may help if it's a biological base rather than corrosion. Do not "scrub" the coin, even with a Q-tip.
Let the acetone soak do what it can, then quit. These little dark areas do not bother a large cent collector nearly as much as a cleaned coin.

It looks hard. At first I thought it was grease. Just be gentile. I've had great success in removing debris and acetone is a good place to start. Best of luck.

I agree ... I would start with a long acetone bath

looks like it's dried on or something...try acetone and maybe gently poke at it with a tooth pick to help get it off if just acetone isn't enough.
Feel free to call me Will.

I would try acetone as well.
Let us know how it works out for you and good luck.

It may be eventually removable, but the surfaces underneath will not have the same toning color as the rest of the coin does.

I can see a few spots where the debris has chipped off, leaving a slightly lighter patina but those area may have retoned a bit. Before using a solvent, you might want to attempt to loosen a bit of the debris with a toothpick to see what the patina looks like underneath. If it is not a great difference, go ahead with a solvent soak. If there is a significant difference in patination, you would probably want to just leave it alone.

Good advice. A wooden toothpick, though, not a plastic one.

I agree with most , long soak in Acetone and while It's still covered with the solvent, gently pick away with toothpick . Mind what they're saying about the patina under the crud .  |

Imo, don't mess with it, patina may come off too, and it will look worse.

There's another item that may help with process of removing/chipping away on the areas. I bought a handful on The Bay and they work great. Unlike a toothpick, these items will not damage the coin. And they are ---- porcupine quills! They have very sharp points, but will not scratch a coin's surface. PG
