[QUOTE="NomDeBoom, post: 3838894, member: 50898"] Don't keep your coins in a metal can if you value them. Why? Most cans are steel, & if moisture gets 'involved', your coins can rust. Also; separate any ferrous objects ( small hardware, pins/buttons, foreign iron based coins, and STEEL Cents) from the herd. Keep them in pottery, ceramic, glass, or other inert material containers. Even coins that are of different metallic compositions can chemically react & discolor each other. Wrap up or pkg. anything you'd like to preserve in some sort of 'approved' material- like acid free paper or some type of non-reactive plastic. And yeah, small magnets are very useful when dealing with 'mystery' metals. I once bought some blackish metal 'chunks' at a swap-meet. They 'Yoostabe' 1/2 a small coffee can of 1950 era pocket change....BEFORE the house burnt down. I could still 'I D' some of the 'burn victims' as Buffalo & Jefferson nickles, Mercury dimes, a few Lincoln cents...as they hadn't totally liquefied in the heat...but, having similar melting points- most were now 'slag'. I eventually refined the silver from some of it, but kept the rest 'as was'. The moral to all this, I suppose, is to 'baby' the good stuff. Store your metals separately. Keep them away from chemicals (salts/acids) & moisture. AND; avoid contact with high heat (450-1250 F) & yer headin' straight into Trouble Town ;-} [/QUOTE]
