Is it good to acetone bath your coins for a while before submitting them to grading? Is that a normal thing to do? Is it something to avoid? What advice do you have regarding this topic? Thanks!

More specifically; modern US coins. Pennies, nickels, dimes, quarters, half dollars, dollars... |

I only use Acetone to remove crud or tape. I never use it on uncirculated coins.

Errers and Varietys.

Probably best to leave good enough alone.

If it looks OK to the eye, leave it alone.

I have rinsed every single submission made to any TPG with acetone. Why risk having something invisible to the eye show up later? Acetone is cheap, simple and effective. |

After I purchased a coin (slabbed) that had no fingerprint when I purchased it but now does, for any coin I submit for grading I dip in acetone.

 that acetone could remove any unseen organic matter so its not a bad idea. also, before spending a lot of $$ grading coins, post them here first |

As I have begun purchasing coins from ebay, I have realized that a lot of coins stored in humid environments or in plastic flips can have residue on the surface. If you slab such a coin without an acetone dip, it will probably be ruined at some point in its lifetime. |

The section under LIBERTY is not a bubble. Just FYI.   I probably should have dipped it for a bit of time.  |

So, should I have acetoned it? I'm submitting a few more coins in the future. Perhaps I should crack this out and re-submit it? Any advice would be welcome. Thanks.

100% acetone is safe for gold and silver. Both a quick rinse and a soak - let it air dry sitting on a clean cloth. DO NOT RUB. Only use "pure" acetone, not nail polish remover.
For copper coins, there is a scientific paper that identifies conditions under which Hydrochloric acid crystals form - but it's not conditions anywhere near what you would create (BRIGHT light, HIGH humidity, and evaporation).
What you need to remember is acetone removes organic residue. Say the oils from a finger. As long as they are removed quickly, it's OK, but acetone won't help once the fingerprint oils have started to etch the surface of the coin. That's permanent.
Many glues, Mucus, Peanut Butter & Jelly. Water spots.
If that was an old water spot it probably won't help. Won't hurt, but won't help.
