i can only comment as to my personal experience and what some of the financial letters i receive state. Concenus seems to be if you are buying metals as a 'chaos' hedge, allocating 10% of your total investment money to metals is a good, safe rule. Silver is also very underpriced compared to gold right now. both metals seem poised to continue their bull runs. thats just my two cents worth. happy investing.
