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.
