If you can save enough nickels and pennies and keep them long enough, you most likely will make more money selling melted metal later on than investing in houses. It certainly will beat savings in a bank account. Such is the power of monetary inflation. The gigantic government debt load all but guarantees a good return on your stash of coins because the only way to pay is to cheapen the money.
The U.S. Mint is facing a problem -- especially during these penny-pinching times. It turns out it costs more to make pennies and nickels than the coins are worth.
