<p>[QUOTE="LukeGob, post: 21796987, member: 73885"]Do as you wish, they are your coins, but none of those are good ideas (in general). Non-AR/AU coins (AE?) are protected by their patina. Coating them in something else to seal them can, & almost certainly will, also seal in things like moisture that will damage it. There are exceptions; I've waxed stuff like a Valentinian III, CONCORDIA AVG, Vict w/2-Wr, from Constantinople with a bit of "crumbly patina" bc = rare coin (mint) in decent shape that won't be if not stabilized. But just in general, there is no reason to do anything to protect your bronze/copper. Even/especially with a rare or valuable coin as it will only hurt the value. Doing what you're describing to AE coins is a measure of last resort to save a coin from some harmful corrosion (yes, I know what "patina" technically is). A decent flip & reasonable climate control are all your AE coins really need if you leave them alone (& even the flip isn't really necessary). Hope that helps.[/QUOTE]</p><p><br /></p>
