Should I stockpile nickels?
Trying to engage in arbitrage with the metal in nickels (which was actually worth more than a nickel already, last I checked) is cute but illegal, and would be more effective at an industrial scale anyway (I don't think you could make it cost-effective at an individual level). There are more effective inflation hedges than nickels and booze. Some of them even earn you interest. You could at least consider a more traditional commodities play - it's certainly a popular strategy these days. A lot of people shoot for gold, as it's a traditional hedge in a crisis, but there are concerns that particular market is overheated, so you might consider alternatives to that. Normal equities (i.e. the stock market) usually work out okay in an inflationary environment, and can earn you a return as they're doing so.... and it's not like commodities aren't volatile and subject to the whims of the world economy too. TIPs (inflation-indexed Treasury bonds) are another option with less risk, but also a weaker return (and still have interest rate risks involved, since those aren't directly tied to inflation either).
