Pawn shops base the value of the item on current appraised value, its current condition and the ability to sell the item. Pawnbrokers use research tools that they have at their disposal to determine an item’s value and get you the most money for the item. The appraisal process varies depending on the type of item—for example, jewelry is evaluated differently than a DVD player. All items that pawn shops buy or pawn are tested to ensure that it works properly.
