My thinking is that silver is a better investment, at least for now. It hasn’t tracked up with gold, as it traditionally has, and at $18 an oz. it is good commodity to own and store.
I agree on the silver end. If the economies collapse, it will rise on the relationship to gold. If the economies do not collapse, it will rise on the increased industrial uses (which are many times that of gold.)
And, at $18 an ounce it is more affordable to average joe.
