Murrieta, California, becomes the land of auction opportunity. The experts sift through a lot of dirt, but they find gold. The daughter of an infantryman brings in her father's hand-drawn map of his journey during WW2, and the experience brings Hammer to tears. Meanwhile, Sean meets Kevin the collector, who brings in a 17th century cannon that his wife thinks is trash. Shooter finds a cowboy's dream gun, an 1894 Winchester riffle that the seller purchased for $100. Sean and Shooter test the weapons with the sellers to make sure that they get the correct bang for their buck. The testing proves the items to be very valuable and arouses the idea of a shooting contest between the experts. Hammer wins the shooting contest, proving that, "There ain't no dog like an old dog." Everyone wins big with the auction.
