Given the advice of FerFAL at http://ferfal.blogspot.com/, he's been saying that post-collapse in Argentina, no one was giving spot rates for any certified 24kt gold coin, dealers and pawnshops would only give junk gold rates even for bullion. With that in mind, I don't think that gold coins are worth it and am looking into buying gold chain. It's more portable, divisible, and more tradeable than gold coin or bullion. Does anyone have any sources?
