I can't help but look at the copper rounds and bars that are being sold. They are very pretty. BUT - a 1 oz copper round sells for close to the bid price of an entire pound of copper. For instance I just saw several different 1 oz rounds being offered at from $2.49 to $2.75 each. That's roughly $39.50 to $44 a pound. Current bid on copper is $3.07 a pound. That's one hell of a premium on copper!! Is anyone buying these? And if so - why?
