if i remember hearing correctly, the swiss central bank is selling off alot of gold. They have some of the largest gold reserves in the world... that is probably one factor in the lowering of gold
anyways, dont overdo it with the gold or PMs, guys... its a pretty volatile commodity, not very liquid, often holding real reserves requires an upkeep fee, but even if it doesnt, its really not good when it comes to actual real return on your money. It keeps up with inflation, but over the long run does not outpace it.
if you must invest in gold or silver, do what ron paul does and invest in mining companies or other gold-related businesses - much more liquid (company shares), and any price rises in gold with lead to an increase in sales and ROE. Or hold a commodity/gold ETF. Liquidity is the key here, otherwise, invest in what you want, im not a CFP or anything.
