Lincoln's Letter

Dale and Blue examine whether a woman who found a letter hidden behind a picture frame stumbled on a lost piece of Abraham Lincoln correspondence that could be worth up to $1 million dollars.  Mike is on a mission to connect a pair of 2,000-year-old pots found in Arkansas to conquistador Hernando de Soto. The guys also look into the value of a jade disc found in a man's backyard, a face carving discovered on the shores of the Chesapeake Bay, and a piece of carved coral that's a perfect match for a prized object in the British Museum.
