Believe it or not I also found a 22-D this week in a bank roll too.
For some unknown reason I gave it an acetone bath and the dark brown patina disappeared.������
Oh Well, I didn't have much invested in this coin

Something must have been put on it to "preserve" it by a previous owner that the acetone removed. Here are two related questions that seem obvious but a definitive answer would be great: Would both of these scenarios be an example of a "Details" graded coin. Meaning;
(1) once it was coated to "preserve" it, is it "details grade"?
(2) is it considered "preserved/conserved" by placing in acetone or improperly cleaned?
Thanks in advance.

I also soaked another common date wheatie in the same bath as the 22-d
both coins lost their normal brown appearance for low grade coins. I also suspected the 22-D was previously cleaned.
Can acetone ever go bad ?
I moved these posts so not to hijack Larry's find, especially since it's a good topic and will likely get quite a few responses.
For starters, how long did you soak your coins, Coinr ? I typically only soak for short periods because most things like glue or crude usually come off with 10 minutes. And....I have had several coins slabbed that had been soaked in acetone, so that in itself will not get a "details" grade,Pete.
I have had coins soak for days (forgot them) in acetone with no adverse effect. There may be residue left on your coin from the "preservative" coating that makes the surface appear dull or hazed. If you have some Verdi care, I would apply it lightly. That should return the luster. It certainly won't hurt the coin any more than it is hurt already.
I'm in full agreement as far as acetone does not remove real toning/patina and doesn't make a coin be "cleaned"..
In fact it's a good way to see if toning was faked.
If a coin was toned with Dellers or held over a match/candle or nose grease (commonly done) or even brown marker the acetone takes it off almost instantly.
There is one kind of fake toning that survives acetone, it's if it was baked on. For example you have an erased polished salmon colored coin with no toning, put it in a cookie size blob of gooey organic mud like you could find around your garden in a spot that's always wet or pond mud with algae in it. Bake that coin in the mud cookie at 500 and it will take on a dark color that won't come off with acetone or anything. It truly improves the coins look. BUT, it's still a cleaned coin and will have a shinny surface and a good TPG should notice that it was cleaned/polished.
This is really good information guys! Thank you! The Lincoln cents that changed color with me after extended soaking in acetone (overnight) were coins that had a good bit of verdigris and the coin probably had some environmental surface damage as well. They were all copper coins too and not in very good condition. After that, I just stick to the quick 15 min acetone soak.
Note, what I said above is for toned circulated coins.
On red or RB cents acetone can/may change the color slightly and don't soak them in dirty acetone or with other dirty coins.
Be sure you have pure acetone not some brand of similar stuff and not nail polish remover. Especially if you resort to anything else like nail polish remover or even normal acetone, be sure to rinse it off well. I'm not sure what's best but I've heard people say alcohol or DI water.
Let's not forget to distinguish copper versus zinc cents.....the zinc cents will definitely be ruined by a long soak in acetone.
GrumpyEd, I rinse all of my BU finds in acetone to prevent fingerprints..nothing else...pure acetone will not leave a residue, or at least nothing harmful.
