(Very) Poor Man's Gold. The post office sells the new Liberty Bell "Forever" stamps, which have no denomination, but are good each for one first-class letter. These are not only convenient (you don't have to remember the latest first-class rate), but they are like gold. They increase in nominal value as the first-class rates increase, and are a hedge against inflation. As with gold, you also lose the use of the money invested in them, so you get no interest; but on the other hand, there does not seem to be any way for the tax people to get you...
