Pawn Stars S18E11 - Rick's Big Shot

When a seller comes in with an overcoat once owned by suspected JFK assassin, Lee Harvey Oswald, will the deal be a stroll on a grassy knoll, or will Rick lose his shot at owning a piece of history? Next, Corey checks out a 30-year-old Gibson guitar with a factory mistake. Can he pick up a sale, or will he get shredded? Then, a rare Mike Tyson Nintendo game punches into the shop. Can Chum knock out an offer, or will the seller put up a fight? And finally, Rick and Corey head out of the shop and into the desert to check out a restored WWII half-track. Will the father and son duo be able to target a deal, or will it blow up in their faces?
