Silver oz was 11.50 on july 2007 , now it's around 20 USD
But keep in mind that the USD has depreciated a lot
It's funny how we create bubbles after bubbles... like the 2000 Internet bubble... then the Subprimes bubble and now the commodities bubble..
But a serious advice is when you hear people who knows nothing about it starting to say like i'm going to invest in that etc.. ALERT!! time to sell
