I'm aware of some of the disadvantages; my understanding is that if I buy a Krugerrand, it appreciated (even if it's just keeping up with inflation) and I sell it, I need to pay a higher "collectors" tax rate rather than capital gains. However, my understanding is that this is fairly easy to get around, either buy going for a ETF like GLD, buying stock in a company that owns gold 'in the ground'
