We have discussed the ratio of the price in one metal to another metal, particularly the gold to silver ratio, a good deal in prior threads.

A basic problem with this train of thought is it does not account for the premium difference between spot metal price and physical metal price. However, how would you track the long time total cost of multiple metals in order to calculate a total cost ratio? If you wanted to track the ratios between gold, silver, platinum, and palladium, what would be your index? What company or country makes a one ounce round/coin/bar of all four? How would find the historical numbers if you found such a company/country? Which vendors prices should be used?
Ideas and help in this matter would be appreciated.
