on the History Channel has a guy wanting to trade his really expensive looking antique car to the pawn guys for gold. Should be intresting what the tax laws etc. say about this kind of transaction and what the pawn guys do.. Relative as many here I suspect have physical gold and or silver and may be bartering someday the way things are going.
interestingly enough, I know someone who did that for investment purposes. he bought a few cases of rather expensive scotch (15 years old i think or something to that effect). held on to it for a few years, then tripled his money.
