S3·E24 Striking a Chord

The Pawn Stars are presented with a rare 18th century book documenting the first laws of congress, but things change after discovering a possible connection to the Declaration of Independence. Can the gang empty their treasury for this historic page-turner or will the deal be vetoed? Then, Rick and Chumlee come across an extremely rare handmade Gibson mandolin from the early 1900s. Potentially worth over $100,000, will negotiations call for an encore or end on a sour note? And later, a man brings in a "high-tech" robot from the 1980s. Will the guys buy this talkative techno-tot or will the batteries for the deal run out of juice?
