I have dug some decent looking old copper indian head cents and other toasted copper or nickel coins. I'm not looking to clean them, I'm looking to preserve them/ keeping them from crumbling or the edges breaking off revealing a white-ish looking broken edge
Is there anything I can treat these with? I heard that olive oil is a no-no.
Some sort of wax?
thanks
