Lately, I've read some articles about the gold/silver ratio and how it should go back to the "normal" 16X ratio.
I believe we won't see this for some time, as national bank reserves around the globe create artificial gold rarity by stocking thousands of pounds of gold. In nature, gold is about 17 times more rare than silver, but the fact that government are stocking gold and NOT silver contribues to make gold even more rare, hence making the ratio bigger.
I believe the situation will only change when the economic crisis will be so huge that ordinary people will be buying silver.
Then, after that, copper will be the next thing.
Follow the money. Right now it is gold. If you are one step ahead you buy silver too. If you are two steps ahead, you buy copper and other base metals.
My two 98% copper cents.
