Soaked Barber Quarter Result.

Yes, too bad about the reverse. I thought the black stuff on the reverse was toning, apparently it was just gunk because it came off with a distilled water and acetone soak, neither which affect toning. The front looks improved. The reverse kind of wrecks it. Not too bad of a buy for $12 though with VF details. I forgot the link to the original since I didn't take a picture first:

Actually, I don't think that is verdigris. Usually green stuff on non-coppers is PVC damage but soaked this for while in acetone and distilled water. I soaked it over night for a couple nights. I am thinking this just might be toning. Maybe it was a dig? That turns coins different colors. I have used verdigris on nickels and it turned kind of greasy. I only use Verdi-care on coppers even though it says you can use it on any coin. I know I was soaking this coin along with some gunked up V-Nickels together which didn't seem like a good idea since stuff from one coin can go on another. I had the same thing happening soaking a worthless foreign dime with a corroded steel cent. I had to re-soak stuff but this red and green stuff appears to be part of this coin and will not come off from soaking overnight.
