Here at Azusa Pawn, we calculate the value of an item based on a few factors, including the condition of the item, the appraised value, and its current market value. We have several research tools at our disposal, and always do our best to give the best prices available.
That said, customers should understand that every item is evaluated differently. For example, a gold coin can be appraised based on the value of the gold, or on the value of rarity of the coin itself. Also, jewelry will be evaluated differently from an iPhone, which will be evaluated differently from, say a power tool, and so on. Some items like collectibles and antiques can gain value over time, while electronics tend to quickly lose value. As you can see, many factors influence how your item will be valued.
