The Pawn Stars are flying high when a panel off the world's fastest airplane, the SR-71 Blackbird, soars by the shop. A supersonic spy jet from the Cold War, will the guys have the intelligence to make a deal? Then, a solid bronze 16th century cannon fires into the shop. Specially made for use on ships, can the guys battle on the high seas for this antique weapon or will the deal sink their fortunes? And later, a customer brings in a vintage pair of gigantic Levis jeans. Used as a display in stores, will Rick and Chum wear the pants in this deal or will they need to button up their skills?

The Pawn Stars try to cash in when a seller presents them with rare $1 and $5 bills from the 1800's. Will they see dollar signs or will the asking price break the bank? Then, the guys plug their ears when a Big Bang Cannon pops in. A tiny toy that makes a big boom, but will it work? And later, a guy pings the shop with a memento given to U.S. sailors who sank U-68, Germany's most feared WWII submarine. Will Rick set his depth charges on "buy" or let this deal sink to the bottom?
