Declaration of Dopeness - S14.E16

Brew up a hot cup of joe with the Pawn Stars when a Civil War era carbine shows up with a "coffee grinder" in the shoulder stock. Will Rick bite the bullet and make a sale, or misfire on making a deal? Later, a vintage skateboard deck shows up in the shop. Will Chum skate off into the sunset or lose his footing and land flat on a no sale?
