The price of silver has dropped around $2 in the last month, currently at $16.58 / ounce. It may be a good time to buy some for use in bartering some day.
One of the good things about buying silver is, you're trading paper money for hard assets. If our economy goes kaput, paper money will be next to worthless, but hard assets such as silver and gold will always have value.
