Actually this raises a very interesting point. As a silver bull I hold silver as a fiat money alternative that will hold vlaue. This does raise the question of the type of the silver we hold. I have been buying unallocated or now pool silver at the perth mint but if the day comes when I need to use this stuff for "trading" it will be interesting as I may not have the correct denimination by which to trade. I have always read it is good to consider Physical gold/silver in terms of what how may Kg's you own not the fiat equivalent but perhaps I need to think more about the breakdown of that physicalm now.........
