Found this while looking for my double 00 2004. forgot i kept this. Its pretty neat. A flow of metal circles both 00's. Its a shame that there is something on the coin. obverse in poor shape. What looks to me as "C" in Queens hair??? Also huge metal dot by queens ear? I want to clean this. Should i use acetone and will acetone work to clean this? Someone told me to use hot peroxide. Does that work for cleaning and is it harmless to the coins??
