Caution: The acetone can melt or fog plastic, so be very careful to keep it away from holders and TPG slabs until the acetone has evaporated. Ditto loupes, phones, and staplers etc. One drop, two seconds on a snap-tite.  |

If you dip in acetone, will it stop any possible toning in the future? John1  |

No. Toning is simply pretty rust. Acetone dissolves many contaminants, but doesn't interact with the metal or the tone. If anything it might allow toning.

Would this be a good idea to do for all my coins before I put them into the AirTite holders? Yes. I would. Quote:Caution: The acetone can melt or fog plastic, so be very careful to keep it away from holders and TPG slabs until the acetone has evaporated. Quote:

It is safe to use acetone with polypropylene(#5 plastic/PP) but avoid other types of plastic.

No, it has removed any organic material on the surfaces including any oils that could be helping to keep air and moisture away from the coin surfaces. Since the metal is now completely exposed (assuming no toning) toning is probably now MORE likely unless it is kept in a dry enclosed environment. |

Wow.. agree that is quite a difference just from an "acetone" bath..
I agree it looks 1000% better..
But if you then sent in this coin for grading, would it perhaps come back as "Cleaned", which could actually reduce the value?
Just trying to weigh the pros and cons of doing the acetone bath...

An acetone bath is not considered cleaning by TPGs. Just don't use a tool or brush.
Soak, dissolve, swish and repeat.

The Bolivian coin would not receive a Details grade for a dip in acetone but it would receive a Details grade for the old wiping/cleaning it received at some point in its past history which left it covered in hairline scratches that were obscured in the "before" photos.

I agree with biokemist6 , but why does that coin that was only in acetone look like it was in a silver dip ? I have never gotten that kind of results from an acetone bath !  |

Just make sure to keep acetone away from plastic materials; plastics can be ruined by the solvent power of acetone.
