Silent and Deadly

The Pawn Stars are on hallowed ground when a piece of marble from Abraham Lincoln's tomb enters the shop. Without any documentation to authenticate the item, can Rick trust the seller to be honest like Abe or will the negotiation die a quick death? Then, a seller comes in with an antique African sword apparently used for beheadings. Will the guys lose their minds over this piece and buy it, or will they not be sharp enough to execute a deal? And later, Chumlee and the Old Man are speechless when a nearly hundred-year-old Charlie Chaplin wind-up doll tramps into the shop. Will they manage to make a blockbuster buy, or will this negotiation turn into a comedy of errors?
