After 73 Years, Rare Nickel Reappears A 1913 nickel has long been a sort of Holy Grail of coin collecting. Only five Liberty Nickels were ever made. The locations of four of them have been known for some time. But at a convention of coin collectors in Baltimore Wednesday, the secret of the missing fifth Liberty Nickel was revealed. Michele Norris talks with Donn Pearlman, a coin collector and former member of the American Numismatic Association's Board of Directors.
