A quick way to double your money -- is to convert it to pennies. Seems it costs two cents to make a penny these days -- thanks to the price of zinc.
Zinc replaced copper as the metal for pennies years ago when copper got too expensive.
The overpriced coins are the target of penny pinching politicians.
Bills in both the House and Senate would make it easier to switch to cheaper metals to pound out pennies. But the main supplier of the expensive zinc is spending a pretty penny lobbying Congress to keep things the way they are. (azcentral.com)
