The giveaway is on the rare stuff. For instance on that episode, they had a signed lottery ticket by George Washington. The expert shows up and knows everything about it at one glance, all the history of that lottery, what it was for, what happened, etc. Complete bullshit. What happened was the expert owned the lottery ticket, brought it to the shop, and they faked that the other guy owned it. The expert got called in from the parking lot, and they shot the next scene with the expert telling everybody about his own damn lottery ticket.
The whole show's b.s.
Don't you think someone could have brought it in for real, and when they call for the expert, they describe the item. The expert then researches it before coming in.
That's how I've figured it works.
I don't think the entire show is BS. I can tell which parts are scripted and which are not, but I do think that most items are real and actually brought in. I think everyone in the shop knows the items that are coming in well beforehand, but that they are actually brought in by real people.
