Prethen, what method did you use to clean with acetone?

OT: Semantics and grammar
My resident English major has informed me that this wasn't a particularly well-constructed sentence. [Duh]
The subject of the dependent clause was someone. She--the one who cleaned the coin--could be concluded to refer to someone, Maryhm, or her benefactor.
Upon first reading the sentence, my consultant also believed I was accusing Maryhm of cleaning the coin. She soon added that grammatically, Maryhm's benefactor was the most-likely culprit.
I guess that's why I married her. (no, not Maryhm's benefactor--my consultant!)
I'll agree it was ambiguous and I understand your interpretation. But I guess we'll have to agree to disagree on this point as well.
It's been fun sparring with you. No hard feelings, I hope.

I bought 100% acetone from the local hardware store. I used a glass pudding bowl and filled the bowl enough to cover any coin(s) I placed in the bowl. I don't place too much in there as it just a waste, however you want to have the coins totally immersed. If I only plan on leaving the coins in there for several minutes to several hours, this should work fine. If I want to leave them in there several days, I use a jar with a lid that can seal in the liquid from evaporating. I use a cotton swap to lightly dab, and if necessary, lightly swab at affected areas. I place the coin on a cotton towel, but it's usually dry with help from the atmosphere pretty quickly. You might want to run the coin under pure/distilled water to wash any contaminants off and then do a quick acetone dip and air dry.
I've done this many times and no problems. There are coins though that can't be helped by this process. Just don't do anything abrasive with them.

I asked on 3 other coin forums and did some googling. I decided to try a short acetone bath. It's sitting in there right now and I can already see that it's eaten off most of the green. I'll post the after pics tomorrow.

It's easiest to see around the top right rim of the coin.

I think I would have tried to spot clean with a q-tip before I dipped that coin.

Immersing in acetone is in no way the same as "dipping a coin". Acetone can remove plastecized contaminants; dipping uses chemicals to strip away tarnish/toning and a layer of metal.

It looks like you did a good job. I think that technically (ignoring the harsh cleaning) the coin is an AU58 based on chatter in the fields on on Liberty's cheek. I believe the coin has seen some circulation to warrant a circulated grade.

But if you consider the harsh cleaning, what kind of grade is it?

I net it as XF. Remember, when you're asking someone to assign a grade, you're essentially asking the person to price the coin.
