Since the last financial meltdown, silver has handily outperformed gold, industrial use jargon notwithstanding. (Sept '08 silver = $10, Aug '11 silver = $40... Sept '08 gold = $800, Aug '11 gold = $1700 )
Gold is overvalued in that its 'flight to safety' factor has added to what its real value in FRNs is.
I don't buy anything based on the psychological factor because that can be manipulated far too easily in either direction, therefore I'm holding for the bottom in silver this month to stock up on a couple of monster boxes.
Silver will again outperform gold against the USD as we look back on this latest financial meltdown simply because it's currently undervalued against the USD and gold is not.
My 2 cents, FWIW, YMMV.
