I though that acetone was not reactive with coin medals, however I am leaning towards the fact that copper may in fact have some reaction. Everytime I send a copper coin into PCGS for grading I have been giving is a soak in acetone. I have had a very hard time getting unc copper in thier holder after doing this. Seems to do something to the color or at least PCGS thinks so. More so on lincolns than Indian head cents.

Oh geeze! Why haven't I been doing this? Fantastic idea. So how long do you bathe your new acquisitions? I want to copy cat you.
I have had great success using acetone on all my silver coins before submitting them for grading. I buy my acetone at Wal-mart in the paint supply section and have never had any problems.
Can I use acetone on a Jefferson without damaging it? I've had great success with using it on my silver coins. Never tried it with any other composition and I haven't located a thread on acetone and nickels.
Thanks!

Acetone should be safe for a nickel.

I have been doing that because of something you said in a thread regarding alcohol and distilled water. I tend to place the coin in the acetone. After the soak, I take it out, holding the coin by the rim and wearing some gloves, pour alcohol over the coin. Isopropyl, right? I use 91%. And then I finalize the rinse with distilled water. Does that sound right?

Why not just rinse with acetone a couple of times?

Putting acetone on a coin will forever change the way a coin looks, you have to decide if it is for better or worse. It changes the color of copper, not nickel and silver so much.-----BigE

If the coin has a green oily film from long term storage in a PVC flip, you don't really have much choice if you want to save the coin from further degradation.

Whether you remove crud from a coin with water, or with acetone, neither reacts with the metal. No change takes place with the actual coin. Conservationists use it, possible even the mint.
If it bothers you, disclose it. But my thought is this: If PCGS had a problem with it, they would not slab coins having an acetone bath.
The air can cause more changes in the appearance of a coin than acetone. It depends a lot on the purity of the metal itself.

lol No CVS in my town either, but I will look around and see what I come up with.
So can you or should you NOT put copper in acetone?
