I never had any luck with these dark Nickels . Do you see any surface crud ,If so give it a soak in Acetone and see if you can safely loosen it up . If that doesn't work then wait for others to give you their ideas .  |

I would leave it just like it is.
Once a cucumber becomes a pickle it can't become a cucumber again.

Don't touch it...
Unless you are an expert, nothing you can do will help and will almost certainly further damage the coin and reduce it's value.

24 hours in distilled water, let dry a few days, then 2 hours in xylene and call it a day. I wouldn't use acetone, it will probably dehydrate the residue and probably make it uglier.

I've seen coins worse than this restored at ICG. The person who does the work (Mike) was one of the founders of NCS! AFAIK, ICG still does not charge extra for this service. Just write 'Please Conserve" on the form when you mail it in.

Thanks afewmorecents. I've never heard that before.
I would definitely be in the leave it alone camp for this buffalo.

Would soap and warm water be an option? Maybe a soap with no additives, like Cetaphil. I know there's some coins I'd be hesitant to handle for fear of catching something unless they were first given a little bath.

Will this combo/procedure also be effective on copper like Indian Head or Lincoln Head cents having the same type of dark-looking encrusted crud? Also, would this process leave these copper coins free of any nasty aftereffects resulting from contact with each of these solvents? I don't want to change the direction of this thread from nickel to copper but the baked on black crud is the common factor to tie up these two themes. In summary, if water/xylol will not budge the black stuff off either the nickel or copper substrates, what would be a last ditch effort to try? |

I've found Jeffersons that look like that - acetone and liquid soap and water barley do anything to help it. Just leave as is - looks fine.
