Minus about a dozen easily-attributable coins that I picked out early, these are the "best of" of ~300 cheapie uncleaned coins I purchased in various small lots [primarily from eBay auctions] back in 2005-2006. Olive oil treament for over 10 years. I'm surprised at how clean and attributable many of them are -- ~40% overall from the orignal batch. (The biggest diameter coins, however, tend toward near-slugs.) Plus there's all kinds of variety I'm not seeing in current uncleaned lots! These coins have been rinsed and soaked w/soap and tap water a few times today to pull of the olive oil. Plan is to soak in distilled water w/weekly changes to really clean them off. After that, manual work. Does anyone happen to have recommendations and/or prior experience on cleaning off oil-soaked coins like this?
