Season 1

A mysterious disc found in the Sulphur Fork River brings a surprising outcome.

While Blue and Mike examine what looks like an ancient axe, Dale inspects an artifact found in a storage locker which may be tied to a brutal practice used on slaves. Plus, a wooden alligator surfaces that could link the Aborigines to America, and a man’s hand-carved pipe causes speculation on whether the U.S. was once the mythical homeland of the Aztecs.

Dale meets a man who wants to prove he found the original knife of folk hero Jim Bowie, but they get an even bigger surprise. Plus, an alleged Viking artifact found in Maine, a possible Mayan idol, and what looks like a weaponized bracelet found on a man’s land in Texas.

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 try to uncover why and how medieval scale armor was abandoned in the Arizona desert. Plus, they investigate an artifact that could connect to early Christianity, a sword found in a well, a curious clasp, and a ring found in a Los Angeles tree root whose owner thinks it could be Aztec.
