In the season finale, Curt Doussett and Kinga Philipps challenge residents of Orange County, Calif., to come up with their most precious lost treasures at the Bowers Museum of Cultural Art in Santa Ana. Kinga has no problem finding two great prospects: stone bowls that are possibly prehistoric and a sword and pistol from a 19th century sea captain. Curt spies a set of rare Native American baskets in excellent condition from the Owens Valley Paiute Indians, probably made between 1910 to 1940.
