a bit late on this one, but i do hold the perspective that the pandas are the best form of bullion, seems like yennus & co has really summed it up well, also the venn diagram is classic, should be in textbooks!
For me, Australians are in business with China whether we like it or not, both the Americans and Europeans have trouble with their collective economies which will be close to impossible to solve, in the new world (or the current one actually), the Chinese have the money to spend and thats why the pandas will be the most liquid/valuable in the future.
With everyone else paying off their debts, the Chinese are still arriving with cash in hand and the first bullion that they would want is pandas. Why dont they buy pandas at home you ask? because they would have run out because of people like us : )
Without a doubt i would spend mt 1600 on pandas, any form of pandas actually, hope that helps mate.
