I will sort out pennies that I naturally accumulate, but will not bother going to the bank. I do like copper, though.
I have been wondering for a long time regarding the issue you brought up vis a vis Ann Barnhart's latest, Offdalip.
Some years ago there was a rumor that a big player in Germany took delivery on a gold contract that was underwater--in other words, they asked for delivery of a contract ABOVE the strike price, reputedly testing the waters.
That was back when gold was absurdly cheap, and tests like that are probably the reason that gold ever started its upward ascent. Had it stayed cheap, more folks would have taken delivery, and some would have demanded taking physical custody.
Barnhart is correct, all they give you is a stupid receipt. But, there is a process in place for taking physical custody. It is fairly long, complex, and expensive--you have to pay for something like Brinks security to pick it up.
But it can be done. Jim Sinclair posted all the steps one day, and it's probably worth a repost if I have time some time.
Not suggesting going through the commodities markets to buy metals--or anything else. Just speculating on what would happen if enough people did...
Gold is probably reasonably priced. I'm questioning other commodities.
