I got this page from the mints website. http://catalog.usmint.gov/wcsstore/ConsumerDirect/images/catalog/en_US/GoldCoinGrid.pdf It is the pricing structure for gold coins. On the left side it has the average price of gold. I am assuming this is the weekly average. Per this chart I am assuming that the price of the 2011 Proof Buffalo will be $1760. Do you think I am correct? Thanks
