Sean Rich, a former recurring expert on Pawn Stars, branches off into his own series for the National Geographic Channel. Sean and his team of experts travel all over the United States appraising antique military weapons for auction. The weapons can include guns, cannons, swords, axes, etc. Some weapons are determined to be fakes, or are just in such bad condition that they won’t even accept them for the auction. Meanwhile, other weapons are tested to see if they can still fire. If they do still fire, the working theory is that they will get more money for it at the auction.
