Does acetone have a shelf life?

You can do it either way Cliff. It does not hurt to let the coins soak. It all depends on the severity of the verdigris. However, here is all the info you should need on it:

Thanks a million Bob. And thanks for the link.
I'll look at it more closely tonight and it will put my mind at ease knowing what is recommended.

Edit: Couldn't wait.
I notice it says "Not Recommended for proof coins."
I have a 1950 proof set, Details Grade from improper storage from the previous owner (they have some Verdi on them) that I think would benefit from Verdi-care.
In this case would it be ok to apply the Verdi care, since they are already details grade?

That's a tough call Cliff. Even though yours may grade out as 'Details' I wouldn't recommend doing any more damage to that set than is already done...especially a very early proof set.

I would say NO Cliff. When I use it on BU coins with small spots it lightens the coin from orange to gold. Your Proof will then come back ""Cleaned""

Thanks guys. That's very good information to know.
I'm glad I asked because I would have thought that it wouldn't hurt the coin more since it is already details grade with a light cloudy surface as well as the Verdi.

Maybe a moderator can/should move this info to a separate thread so more people can find it and benefit.

Anybody wanting to try the vinegar and salt approach can get a good idea of what the coins will look like, below.

Thank you for showing us what "not" to do! My thoughts are, if you think you have something really rare or valuable, ask the LCF before you do ANYTHING to it. Then if you are unsure about doing it yourself, consider finding an expert to do it for you. I saw something on a thread where TPG's were offering coin conservation (I think) that may be the way to go.
