A couple of things off the top of my head. A while back I called a local dealer and asked to purchase some bullion. He told me that he would love to but could not get it. As I also understand, the supply of gold includes what is available in the ground and it does not matter if it is dug up or not? I have also read some interesting articles on how governments lease gold and have overstated their reserves.
