can gold and silver get rusty? and how to polish?
parlanchina asked:
i have a few gold and silver coins. i noticed the silver ones start becoming black all over. i also have a few silver bars closed in a plastic bag so no way air to get in, but even they start getting a bit black inside. i wonder why?? also how about gold? on two of my gold going i saw small rusty dots, is that normal? what to do to prevent this?
By the way, i am 100% sure the gold is a real gold because it is Pamp Suisse (and has Assay Card)
