for one gold could never again be currency except in very controlled situations....Reason being is there is not enough of it to sustain the US economy;s GDP of 14 trillion dollars...Do you know fort knox only has 300 billion in gold reserves? so how would it be possible? about those gold chain infomercials..that puts questions in my mind too,but either way they are robbing the people who use them....they are nothing more than a pawn shop taking advantage of the situation..no matter if gold does crash to 600 an ounce they will still make out because the are only melting the junk and not the prizes that go into there inboxes,like old gold watches and jewlery ect..thats worth much more than the weighted value of the gold.
