Is it safe to use metal polishes like silver or copper cleaners on rare coins?

DEFINITELY NOT! Cleaning your coins will make them look un-natural, and will make them worthless in the eyes of collectors. And using anything abrasive (like polishes) will also leave tiny hairline scratches on the surfaces of the coin -- making them even more worthless. If you do this, you will likely turn your valuable rare coins into worthless slugs.
