(MONEY Magazine) – 5¢ 6.4¢

» Thanks to a recent spurt in nickel prices, the metal in a 5¢ coin (25% nickel and 75% copper) is now worth more than the coin itself. But don't get any bright ideas: The U.S. mint recently issued rules that make it illegal to melt down coins. And what are you going to do with a vat of molten metal anyway?

NOTE: Prices as of Jan. 18. SOURCE: London Metal Exchange.
