Acetone Soaking Coins In Batches?

How are you managing this without the coins laying flat where the acetone can't do its' work?

Keep in mind that the acetone is sacrificial. I haven't done much experimentation, but even in this scenario you're not going to be able to reuse it to any great extent. And each coin has to have its' own dedicated rinse in clean acetone as a final step, or you're undoing the whole process.

So I hear people say they use acetone and verdicare. I've heard some say they use both. I have a lot of pennies with verdigris on them..what's better to use?

Acetone will not remove verdigris. VC is too expensive for a mass removal project.

Sort of a lot of trouble if those coins are not worth a lot. As you have already read, what is on one coin can be transferred to others in that Acetone as it evaporates. Why not take the time and just dip one at a time in a small jar with Acetone and then into another with distilled water or more Acetone. Might take longer but you would get the best results.

Some time ago I did exactly that. Put several different types of coins in a jar with Acetone. I did it due to a post somewhere about Acetone effecting Copper. I got rid of that photo of the results but for some reason some of the coins were effected by possibly the mixture of materials in the same Acetone. Sure wish I kept that photo. Can't remember all the coins but I think one was a Dime, a Nickel, Large Cent, etc. I do remember some of the coins became discolored. No additional Acetone would fix this though. Sure wish Jbuck could find that old post and photo.

it is better to do one coin at a time. Better for the coin that is ? And isn't that what you care about ? The coin ?

My feelings about Photobucket - whom I've been with for a long time - aren't quite up to "hate" yet but they're trending in that direction. Chances are Carl's images are still up there, and Photobucket has simply changed their URL location. Six or seven times since, the way they do things.
