1953 S Cent

Is acetone safe for this kind of toning? I only want to remove the dirt.
I had a deep blue 1962 5C proof that I bathed in acetone last night and now I just have a 1962 5C...

I'm certainly no coin doctor by any stretch, but acetone won't hurt it. I don't think it's going to do much about the fingerprint though...

Pretty good thread and discussion on this exact topic:

I would leave it be.
its not what you started with it another coin now,,lower value
Nice the way it is. I would enjoy it the way it is.
Not sure the improvements you are hoping for will work on this one.
A bird in the hand.....
As long as you don't allow the acetone to completely evaporate, and rinse the coin thoroughly, acetone shouldn't affect any natural toning. As others have said, the fingerprint, may be set.
It's very interesting that the toning on your proof nickel disappeared after soaking in acetone. Acetone is an organic solvent and shouldn't affect any inorganic reaction products on the coins surface. (I'll let the chemists provide the details). By chance, do you have any before and after pics?
@Oldhoopster . I did take one before I soaked it and the Washington pictured together. And it was 1960 not 62.
The Washington came back from our host PVC residue Do not holder.
The middle pic is the after (coffee not down yet) kinda looks black but in real life looks like a nickel
If the appearance of the nickel changed (hard to tell for sure from the picture, though I do see some difference) than the coin had organic residues (from finger oils, smoke, or other environmental contaminant). Acetone will not remove the fingerprint on the cent. I will say though, that if a print is put on a coin, then immediately dipped/soaked in acetone, it can be removed....any length of time though, and the acids will etch the surface. Cheers, RickO
Yes, and copper even more subject and more rapidly so than silver.
Well, just Love coins, period.
I use methylene chloride for pvc. Unless you are a chemist, you can't get residue-free acetone.
The pictures were not purposeful and do no justice to the before nickel. It was a much darker blue and lighter blue in the fields. It looked really nice and thought I would just clean it up a bit. But, it went from blue to nickel within seconds.
Its not the first blue one I've come across from the proof packs, just was the best. So it must be somewhat common maybe this collector lived next to a chemical plant or The Blue Lakes Trail in the Mt. Sneffels Wilderness.
"It was a much darker blue and lighter blue in the fields. It looked really nice and thought I would just clean it up a bit. But, it went from blue to nickel within seconds."
And there you have it.
