Rick has said it time and time again, if he bought items for what they are worth, they would be out of business. People always want full retail value for their items. If you desire that much, don't take your item to a pawn shop, take it to an auction and pay the fees. You may think that they are ripping someone off by buying an item for $500 and selling it for $1,000. But think of this, take a look around the store and look at their massive inventory. Think of all the money they have tied up in purchases that may or may not sell. They had one item sit in their shop 15 years before selling! Making a 50% profit on one item, sometimes just covers for a miss or bust on another.
I buy and sell vintage entertainment memorabilia, and must buy items at minimal cost to make sure I make overhead. No item bought is a guaranteed sale.
