[Winner] Debatable [Silver Details] As of this writing, the value of the largest gold ETF (GLD) is 7.75 times as much as the largest silver ETF (SLV) ($37.57B vs $4.85B). If people invested as much in silver as gold (by selling some gold and buying silver, in the ETFs), that would result in $16.36B invested in silver, which would require buying 1.1 billion ounces (likely more than is currently available), which would drive prices much higher (Warren Buffett's purchase of 130 million ounces in 1997-1998 caused the price to spike to 80% over 7 months). [Gold Details] Gold investors could simply argue that gold is more valuable than silver, and more perceived as money than silver, and therefore one should devote a much smaller amount of their precious metals investment to silver.
