regularguy Valued Member United States 187 Posts	Posted 07/10/2011 12:28 pm I would try a quick dip in a liquid silver jewelry cleaner. I have had some good results doing this on some low value, higher quality coins for my collection. If you are going to keep the coin and add it to your collection, do what you want to with it. If someone cleans coins to enjoy in their own collection, so what. If someone cleans coins to deceive another person, then that is bad. Report this Post to the Staff

That is true but the most important point that most people miss is the fact that selecting the coin for improvement potential is the key detail. Many collectors have thought at one time or another that they could help a coin by cleaning it a little bit but therein lies the problem- the vast majority of collector-grade cleaned coins(read: problem coins) on the market were once cleaned by an owner who thought they were "improving" the coin. You cannot just "hope" that the coin's eye appeal will be improved, you have to know it will be improved before you even touch the coin. Experience is the only thing that will keep you from messing up coins by cleaning them but that experience is usually gained by also messing up alot of coins Report this Post to the Staff

just carl Bedrock of the Community United States 20753 Posts	Posted 07/11/2011 08:44 am Quote: polishing compound and a rag, rub like crazy Use the ones found in the auto aisles at most stores. Works on cars so why not on a coin? Quote: Or maybe a hardened steel brush on a drill? No not a stell one, you have to use a Silver Wire Wheel on a Silver coin. If your really intent on cleaning that coin, try that jewlery cleaner sold at Walmart in the Jewlery department. Usually works but may make the coin turn colors later. So if you really do, rinse well with distilled water. Report this Post to the Staff

flotsam Valued Member United States 115 Posts	Posted 07/11/2011 12:17 pm Interesting topic. I just want to know how to undo someone else's damage. Copper when its been cleaned looks just horrible. As an experiment on a low buck cleaned cent I applied heat. A small amount of heat produces some interesting rainbow toning. I would never pay the kind of money some of these shysters want for rainbow toned coins nor are they all that desirable. Once you see how a bit of heat or perhaps some chemical persuasion causes toning its all a ripoff. Report this Post to the Staff

It is not that simple if you know what you are looking at. Natural toning is defined by slow kinetics of the oxidation reaction. Applying heat or adding chemicals exponentially increases the kinetics of the reaction which does result in a different toning scheme. Report this Post to the Staff
