Back in 2009 when Pawn Stars first appeared, my old gun collector friend, Sean Rich, was the "gun expert" that Rick always called to verify whatever gun was being offed for sale. (The guns were from Rick's collection, as I recall !) . At the start each of the four Pawn Stars was paid $4,000 per episode, I was told, and other friends I knew from the Las Vegas gun show were hired as actors to bring guns into the shop to sell. Other people regularly appearing, like the Clark County Museum guy , Hall-Patton, and the book lady and the toy shop owner, etc. are paid a nice stipend each time they appear and are allowed to research the question before they announce their opinions. It's entertainment, guys, not facts ! Ed.
