highroller4321 Valued Member United States 187 Posts	Posted 03/20/2009 11:30 pm Hi Everyone I recently aquired an almost complete set of lincoln cents. Only coin missing is the 09 S vdb. The coins where stored in an older book that had plastic sleeves stored in plastic. Since this was older plastic it contains the chemical PVC in it. Needless to say most of the coins have a green rim and weird film like substance covering the coin I have read on here in several differnt threads that acetone can somtimes be used to remove the green and the film. My question is Is Acetone safe to be used on all coins? I dont want to damage the coins...exspecially the 1922 NO D Also how long should each coin be left in the Acetone? Since I have several coins that need the green removed how often should I change the acteone before putting a differnt coin? If you dont reccomend acetone that what do you reccomend? Thanks for the help and suggetions HR Report this Post to the Staff

vermontensium Moderator United States 16677 Posts	Posted 03/20/2009 11:36 pm There are products specifically made to remove PVC residue but I would think Acetone would be fine. I have only used it a couple times and am kind of an amateur when it comes to it's usages. BadThad would be the guy or biochemist. Wait for some of our chemists responses. To think the 09-S,& 14-D are affected with PVC residue swcoin.ecrater.com Report this Post to the Staff
Peter THOMAS Pillar of the Community Australia 2830 Posts	Posted 03/21/2009 04:44 am G'DAY, I've never used Acetone to remove anything from coins. Judging by numerous previous threads on CCF, it seems that American collectors often use it, without adverse consequences. I recently had some "cleaning challenges" at home - thankfully, not coin-related. I found that eucalyptus oil can remove some very sticky adhesives, including ones in place for a longish time, AND those which had resisted several previous attempts with alcohol, and other common household solvents. If I had a "green problem", I think I would give earnest consideration to trying eucalyptus oil. Peter in Oz Report this Post to the Staff

mikep Valued Member United States 322 Posts	Posted 03/21/2009 10:16 pm Hi. I've used acetone on a bu wheat I've found that had a sharpie scribble on it. I would pour it in a glass jar with a wide opening let it soak and swirl occasionally. Do not rub the coin with anything. The acetone should break it down and dissolve from the surface. This worked for me and showed no traces of change on the coin. Probably practice on a common date before jumping to the keys. Mike Report this Post to the Staff

BadThad Bedrock of the Community United States 19935 Posts	Posted 03/23/2009 10:28 pm highroller - The green is most likely verdigris from exposure to humidity. Can you take some pictures? Your next step should be soak them INDIVIDUALLY in xylenes. It's a much better solvent for copper than acetone. Lincoln Cent Lover!

highroller4321 Valued Member United States 187 Posts	Posted 03/24/2009 7:56 pm I soaked them individually in acetone so I would do that same with Xylenes. Where is a good place to buy xylenes? I will try to post pictures today or tomorrow. Thanks for the advice Report this Post to the Staff
