I have the reverse working now.
Looks like the stuff leaves a "footprint" exposing its use.
I'll be watching for that from now on.

Yeah, I realize the discoloration is a trade off, but it is waaaay better than the green slime IMHO.
Believe it or not, that will tone down. I owned an 1800 half cent that had been messed with. I put in an coin envelope that was not sulfur free. When I up graded it, about five years later, the coin sold as "normal piece."
A copper coin doctor could make it tone faster. He would fix the whole thing, but you might not like the result.
Because the metal underneath the verdigris has not been exposed to the same conditions as the rest of the coin. So it doesn't have the same toning/coloration.
I did soak the entire surface but I think the verdigris was not allowing what was underneath it to tone at the same pace as the rest of the coin.
Might costs you a point on personal guess
