I don't see anything on that coin that would indicate acetone will help. Acetone removes organic contaminants - PVC, tobacco smoke, etc. The dark areas of your coin are just natural color - the light areas are harshly cleaned with hairlines. No amount of messing with it further is going to improve that.
Just thought I would try. Have been experimenting with acetone dip. I didn't expect to fix a problem coin. Just having fun.
I assume you're speaking of the recent six volume series which, of course, is a fine recommendation, but at this point in time, perhaps the earlier (co-authored) "WB" book would make a better start for the OP even if only because it is available free online. It can be found in the "blog" section of the David Lawrence website.
Just reviewed the book online. Very cool resource. Anyways, mine didn't match any of the listed varieties. Just a plain ole' 1858 O.
So the seller admitted to me that he was the one who used an eraser on the obverse. I could tell it was done, but didn't think he did it. I told him about the observations and opinions posted on here. He said he may buy it back from me because of the issues.
