Pawn Stars Season 5 Episode 30

The Pawn Stars sing “Hail to the Chief” when an autographed collection of presidential memoirs comes into the shop. Written and signed by President Harry S. Truman, will Rick campaign to buy these rare books, or is the seller just not on the same page? Then, Corey and Chumlee are presented with a toy “Robby the Robot” from the 1956 movie, Forbidden Planet. Can this mechanical gizmo automate the deal or will it run out of batteries?
