<p>[QUOTE="Ken Dorney, post: 2272955, member: 76086"]Cleaning coins should always be done by the professionals. If you are not only try your hand with coins you can destroy and not be unhappy about it. I've been dealing for over 25 years but prefer to leave it to those who know more than I do. This humble coin here is the first one I ever cleaned, bought from a junk lot from Francis Rath (likely no list members here who remember him) probably 30 years ago. Turned out OK, but will need another 100 years to tone back down naturally. I do remember experimenting with electrolysis. I know some have great results with it, but my first experiment was not so good. I had a junk lot that I put in together, turned out a nice and really rare Byzantine was in there, potentially worth $500. I left it in the solution too long (or had the power up too high, or combination of all?). When I went back to check it after another 30 minutes, the damned thing had actually dissolved to about 50% of its original size!</p><p><br /></p><p>[ATTACH=full]453014[/ATTACH][/QUOTE]</p><p><br /></p>
