So I invested in some copper rounds, mainly cause I like the designs: and This one. I got them in the mail this week, and today I wondered when was Silver at this price, roughly $3.15 per OZ. I It doesn't look that long ago. Possibly 1970. So why the swing in price for copper (because more of it is needed for the electronics we need?). Could it become a precious metal like silver? Also got me thinking.... Can I take an ounce of pre 1982 pennies roughly 10-16 of them to a bullion dealer and get close to the spot price for them. It makes 16 cents turn into 3 bucks. I've always saved my pre 1982 cents for there copper value. Is it legal to ever cash them in for melt value?
