Do the sellers get an appearance fee or just "get" to be on TV?
I realize all the sellers are prescreened and some are serious while others obviously just wanted to be on TV (like the guys who are "outraged" at "low-ball" offers or "shocked" by an expert's opinion of inauthenticity), but if they get an appearance fee what difference would it make if they take or refuse any offer? A motivated seller would get some money, an unmotivated seller would get free advertising for his/her item ("as seen on Pawn Stars"), an attention seeker would get bragging rights for their "15 Minutes of Fame".
Also, what about residuals for reruns?
