best if you can work with it outdoors...good job!

That coin does appear much better now. As long as you have the Acetone, nothing to loose with a few more attempts. With the Acetone you have always first test it for purity. This is simple. Using a really clean, clear glass dish or even a glass, pour some in it. Allow to evaporate completely. If pure there will be nothing left. If not, usually a faint whitish dust will be there which is the residue from tainted Acetone. And always remember to rinse with distilled water.

Your coin looks much better after the acetone treatment. I have some gunky coins that I'm going to try out after seeing the results you got with your Morgan.

Remember, acetone is a solvent for petroleum based gunk. Some stuff like the tape glue, it will work wonders, other stuff it won't do a thing.

Depends on what it is. Verdigris is a hard green caused by chemical reaction of copper. Verdigone from Bad Thad would be your best bet for that.
There's a soft green caused by breakdown of leather. It can be scraped off with your fingernail or a toothpick, or dissolved in acetone.
Then there's a slimy green that comes from plasticizers. Acetone will generally remove it.

An alternative to acetone that is a stronger organic dissolver and should not affect metal is toluene or xylene. These are related to benzenes and are toxic so use outdoors only. Don't use acid derivatives such as alcohols as these can react with the metals. Toluene is a really good wax dissolver.
Of course test with a lower value silver coin first. I don't think purity should be a concern stuff bought at home depot should be okay.

How about the acetone the ladies use for removing fingernail polish? Same thing?

NO, NO, NO. Read the lables on those. They contain so many different things you will be amazed that fingers don't fall off.   And many don't tell you how much of them is in their product either. |

Gotcha. Thanks for that info. Now the question that comes to mind is will this treatment show up under the new PCGS Secure Plus processing system where they laser scan each coin, not only for identification purposes but also looking for any signs of alteration or treatments, i.e. chemicals, whizzing, AT etc...I haven't seen a list of ALL the things it scans for as far as foreign substances but I know it's quite extensive. For now PCGS is only using it for ultra-rare and rare coins but it will eventually work its way down to standard grading. Would I be inviting a future bodybag if I ever did decide to use acetone on a coin I wanted to submit?

I don't see how acetone could be a problem.
