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.
And because of that, the Obama administration this week asked Congress for permission to change the mix of metal that goes to make pennies and nickels, an expensive recipe that has remained unchanged for more than 30 years.
To be precise, it cost 2.4 cents to make one penny in 2011 and about 11.2 cents for each nickel.
