Where did you get your data?
I found some data at macrotrends which show the average inflation ajusted price of sliver from 1915 to 1970 at about $9.00 per once ($4.00 to $16.00 range) and the average from 1915 to 2013 at about $10 when considering the price spikes of the late 1970's and 2010's.
Keep your bonds!
I will keep my metals:)
With more people on food stamps than live in all of spain we are a vastly overrated country with no hope!
Hows that hope and change working for all you who voted for Bama?
