Most news pennies are spotted. Some spots are brown and some are white. I read it happened during the cleaning of the planchette. I know the experts recommend only acetone or distilled water for cleaning. Can these spots be removed?
When I find a penny without spots I keep it. I have a fair amount of spotless and scratch-free cents. I believe a large part of the Zinc cents will disentigrate eventually. Can the good ones be saved without the same fate?
