tepritts Valued Member United States 306 Posts	Posted 01/07/2010 12:38 pm First, I never clean my coins, but I really need to remove some debris from this coin to check the mintmark. Need your suggestions on how to approach this job. Which would work best: olive oil; xylene; acetone; toluene or something else. I've added some pictures of the coins including several of the date and mintmark. The closeups are from various light angles. Thanks -- Terrell Report this Post to the Staff

tepritts Valued Member United States 306 Posts	Posted 01/07/2010 10:50 pm Looks like an RPM on the mintmark. But I think after cleaning the date and mintmark, it'll be just Machine Doubling. Right now you can't see the metal and flowlines. Terrell Report this Post to the Staff

John1 Moderator United States 56855 Posts	Posted 01/08/2010 07:21 am I don't think it's a RPM. I suggest cleaning from the mildest method first,soap and water and then move on to more harsh methods. Good luck. John1 Edited by John1 01/08/2010 07:22 am Report this Post to the Staff

tepritts Valued Member United States 306 Posts	Posted 01/08/2010 9:00 pm Let me say that I do not recommend cleaning coins. This coin is worth 1 cent prior to cleaning and will be worth the same after I finish. I am trying to get a better view of specific features that are hidden. Here's some pictures of the coin after a wash with water and soap. I was very surprised and pleased with the results. I'm planning on more torture of the coin next week in my lab with other solvents. If there's interest I will post pictures. Terrell Report this Post to the Staff
