danhughes Posted January 18, 2013 Report Share Posted January 18, 2013 Last month, the United States Mint submitted a 400-page report to Congress that could make the coin identification circuitry of our metal detectors obsolete.A move is afoot to save the government big bucks by changing the metal composition of our coins.No longer would a penny be a zincoln. No longer would our dimes and quarters be made from the 92% - 8% copper-nickel ratio we use now.And metal detectors that are programmed to recognize our current coins would be mightily confused with different metal formulations.Is this the future of our United States coinage system?Listen to show #115 at http://thetreasurecorner.com.
