BamaBlue Pillar of the Community United States 624 Posts	Posted 05/03/2013 08:39 am Drsandman2... I'm not familiar with the properties of Xylene. Acetone Will pit copper and copper-clad coins and soaking them even for a short time may not be the best thing to do. However, Silver coins (90%) are immune from any corrosion from Acetone due to a lack of oxygen and hydrogen (e.g., H2O -- water). You could literally store silver coins in Acetone without any impact to the integrity of the surface of the coin. If that's not correct, I'd like to know (I've never had a coin in Acetone for more than 2 weeks). Report this Post to the Staff

You could do the same with copper and copper-clad, if you wish. Don't forget what silver coins are alloyed with. It's not just the copper, it's the presence of water vapor and light to supply the ingredients for the photochemical reaction. Doesn't matter what the copper is capable of if you deny it the other ingredients. And it bears mentioning that acetone is quite miscible, and as a result needs to be stored in airtight fashion or it'll attract its' own water. Report this Post to the Staff
