Rick considers buying an 18th Century cannon that could be worth up to $40,000. But, before he makes an offer, he'll need to verify that it's the real deal by test firing it first. Then, a local woodworker needs cash to keep his business afloat and looks to pawn his 1.5 ton table saw. The Pawn Stars might lose the deal if they can't figure out a way to move it back to the pawn shop. Finally, a guy trying to sell his replica Roman armor strikes out with Corey but gets a second chance as Chumlee tries to negotiate what could be his first and last deal at the shop.

An 1861 Civil War saber finds its way into the shop--but if it's real, why was the blade never sharpened? Then Rick and the owner of a Chuck Berry autographed Fender guitar find themselves on different pages when it comes to bartering over this item. Finally, the Pawn Stars appraise a "1916 National Cash Register." It looks real, but will they pull out the money from their 2009 cash register?

Corey gets into deep water with his dad and "The Old Man" when he buys a 1984 Chris Craft boat without first testing it out. Will he bounce back and make a profit or see his investment sink? Then, an old timer brings Rick an 1849 colt revolver that he forgot to unload! Will Rick add this antique weapon to his pawn shop arsenal, or will the sale backfire? Finally, the Pawn Stars get a chance to buy an incredibly rare 1954 Gretch Guitar previously owned by Robert Duvall.

It's clear that this is no ordinary pawn shop as the Pawn Stars wheel and deal items ranging from an old school Pac-Man to a Medieval Jousting Helmet. If these items are as real as their owner's say they are--they could be worth up to $30,000! Then, an old timer brings in a pristine 1884 Trap Door rifle that the guys buy hoping that it still fires. But, when the gun range owner says that simply firing it could cause a "catastrophic malfunction" the guys decide it's time to bring out their human guinea pig.

Rick buys an old, Mafia favorite the 1962 Lincoln Continental with "suicide doors," but as the repair bills add up, so does the tension between him and the old man. Then, a guy brings in a billfold from 1857 that he found while cleaning out his garage. The best part? It's stuffed with Confederate money. Finally the Pawn Stars get a chance to buy a rare 1942 Gibson L7 guitar that was once played at a birthday party for Al Capone. But, is the seller in tune with what it's really worth?

It's one of the oldest forms of banking, and until the 1950's, it was the leading form of consumer credit in the U.S. Now, the fascinating world and history of the pawn shop is revealed in the 13 episode long series centers on the only family-owned pawn shop in Las Vegas, where three generations of men--grandfather, father and son--entertainingly clash while running the business together, using their sharp-eyed skills to carefully assess the value of items their colorful customers bring in, objects ranging from the obscure to the truly historic.
