Doesn't that allow an arbitrage situation, where you can buy Zimbabwe dollars through official channels and then sell them on E-bay for more than they cost you? Or maybe the "official" exchange rate is depressed through shortages and risk in completing the transaction.

I think supply/demand may get in the way: not that many people need zimbabwean dollars, just some collectors and those who seek them for novelty value. Market will become saturated pretty quickly.

There are also websites that try and pump up the currencies as get rich schemes.[1]
