[QUOTE="desertgem, post: 722189, member: 15199"]It appears like someone tried to clean it by the lines that are on the surface, or is it in plastic? Since it is modern, if a lacquer was applied, most likely it was acrylic and once hardened, would not be affected by acetone or xylene. etc. But it doesn't appear like such was applied as it would not flake off in just certain areas. I suspect the cloudiness is a toning process on the surface, but such areas on proof coins can be caused by chemicals used before striking, and maybe on this one, before the process of gold plating ( I am assuming it is gold plate). Safe answer : Leave it as is, enjoy the thoughts of that year. Unsafe answer: The Dip would be the only possible thing that could [COLOR=Cyan]fix [/COLOR]it or really[COLOR=Red] ruin[/COLOR] it ,IMO. Remember that the silver after your first dips/rinses would be "raw", with no invisible surface patina, and will react rapidly with toning substances if not put into a safe environment. Jim[/QUOTE]
