Suggestions For Cleaning

Much nicer, Biancasdad. At least every time you look at the dollar from now on you won't be thinking to yourself: there's something stuck on that coin. I'll try jewelry cleaner the next time I have a coin like this, thanks to your tests.

Absolutely thanks! I have a couple like this one and I'm gonna give it a try. As SSuperddave says... It's a lost coin anyway. Only bought if for silver anyway.

Wish I saw this thread earlier. Instead of jewelry cleaner you should have looked for a polivit plate. Its a sacrificial metal cleaning plate. You make a solution of warm water and household soda put the plate in the solution and then put the coin in the solution ensuring it touches the plate. The oxidation on the coin is reversed while the metal in the plate is corroded. It can take a corroded silver coin back to new in less than 10 seconds and is ideal for that coin of yours. the great thing is it doesn't involve adding silver as it just simply reverses the oxidation process. You could still try it out on that coin... once you have reversed the oxidation you need to ensure you wash off the electrolytic solution and then dry the coin by washing it in acetone. I believe the plate is made of Zinc.
