I worked in a pawn shop for quite awhile and to answer your question this is how it works. You bring in an item, for conversation sake let's call it a pool cue, they will then usually consult a blue book (for all applicable items that have a blue book printed) to get a general idea of what something is worth and to get any clues to determine authenticity, signatures, determining marks etc. Then they will do an internet search, they usually start with Ebay and use others such as Amazon, Craigslist, and other sites as well to find out what a similar item is actually selling for NOT what is being asked, they want to know how much people are actually paying for items. Then depending on quality, rarity, customer dependability, etc...They will offer up to 50% of what it is selling for on Ebay on items in pristine condition and 50% is actually usually only for brand new items still in sealed packages. The reason they offer 50% of what it is selling for on Ebay is because they then turn around and will sell it for slightly less than it is selling for on Ebay, that is how they keep customers coming in and not buying predominantly online. Now, keep in mind, great customers who have came in before, pawned a lot of things or high dollar items and have never been late can usually expect a little leniency on prices for items being pawned and not sold to the shop because they can rely on them to pick the item up and they don't have to attempt to re-sell it. As far as the T.V show goes, the shop is real as most people know and the guys who work there that you see on the show are the real owners and do put in a little time at the shop but they own others businesses as well in the Las Vegas area. As far as the customers you see on the show, totally fake. They are paid actors and every item you have ever seen come in the shop on that show, they already own it, whether the "customer" said no on the show or not. The way they get these high dollar items is putting out ads to other pawn shops, thrift shops, or just general ads to get them to bring in unique items. Obviously since the show has came on they pretty much stopped that because it was no longer needed as the show gave them all the publicity they want and sometimes you can expect to wait outside for hours just to get inside the shop. Just my educated 2 cents.
