ToddsPoint, , there are many utube video's … look up cleaning silver coins with electrolysis..... Use any adapter under 12 volts.... Mine happens to be a 6 volt. Cut off the ends, add alligator clips. Use tupperware or a pickle jar. 1 cup of hot water, 1 tablespoon reg. salt, make sure you stir until all the salt is dissolved. Don't worry if you don't know which wire is positive... hook a stainless spoon/fork/ to neg. wire and the coin to the positive wire. Drop both in the solution making sure they don't touch each other. Then plug in the adapter, in a few seconds you will see bubbles coming off the coin, if the stainless is bubbling, you have the wires backwards..... Just un-plug the adapter and put the coin in the other clip and also switch the stainless . Plug in again, within a min. the coin should start to bubble. Leave for 5 min. , unplug, rinse coin and rub coin with fingers under running water, if it needs more, do another 5 min. and check again. If you want, you can change your solution when it gets really black, and then start over. You can use a little baking soda with a drop of water to make a paste and gently rub the paste on both side and rinse off. Don't clean the coin too much, you want it to still look old.... Warning, do not clean a valuable coin--let the pro's do it...
