Although I have never used acetone or dip, I have read that after soaking in acetone a rinse with fresh acetone followed by blow drying often leads to positive results. Is there any luster remaining on this piece?

Do you really want that to be your experiment coin? Pay for a professional to do it if you're going to

Quote: Is there any luster remaining on this piece? Yes, a little bit :) Quote: Do you really want that to be your experiment coin? Pay for a professional to do it if you're going to I have full confidence in my capabilities. Acetone doesn't hurt the coin so I have nothing to worry about.

I think you have demonstrated, from what I can see, that acetone can harm a coin. I never believed the blanket statement that acetone can do no harm to a coin.
What I would do now is reach out to Dick Osburn and Brian Cushing, email them some pictures and see if they can offer some advice about conservation. I would also reach out to the Smithsonian's numismatic curator to see if you could speak with someone who conserves the national collection for advice with pictures. Lastly, I would reach out to the staff at Great Collections, Heritage and StacksBowers if you have relationships with them (bought or sold anything with them in the past) and ask advice as to what you can do to preserve it for a future sale down the line. If they help you, consider selling the coin through them when the time comes.

It doesn't look all that different to me, not to disparage your good advice.

Edit to add I really don't understand the advice to email everyone under the sun about it. They don't want to spend all day telling people to send it to PCGS or NGC for conservation and the people that could potentially fix it won't discuss with strangers how to.

I can't figure out wth would have caused that. It looks like a beverage spill or maybe some type of sulfur gas like maybe it sat over a fire place for a period of time. Or it could be a botched AT job. One can't help but think that a coin in that grade would be slabbed if it graded straight. How much did you pay for it?

Acetone is harmless. Soaking a coin in it for three days is a waste of time and acetone. Next question please.

Quote: How much did you pay for it? $614. As for the weird toning, I'm thinking either weird toning or tarnish. Quote: Soaking a coin in it for three days is a waste of time and acetone. It was worth a shot. I think I'm going to take it to an NGC-certified dealer in my area and send it off to NCS. Edit: Just sent an email to Osburn and Cushing, thank you for the suggestion Numismatic_student

Our resident expert coin chemist who invented the much acclaimed Verdi Care is the one who suggests acetone and also xylene. Chemically these cannot react with the metal of this silver coin. Having used acetone now on hundreds of coins with no adverse side affects at all. I have done fewer copper coins and have seen no affects, but some say acetone can give copper a pinkish tint.
And the only thing I see different in the before and after pics is the lighting makes one look different.
