Why should I use Crown Refining instead of a pawn shop, jewelry store or gold buying store?

Simply put you will receive a lot more money using Crown Refining.  When you send us your material you will receive an assay which will tell you what percentages of the different precious metals were found in your material giving you a much more accurate, reliable and valuable result.  Typically 3-5 times more than you would receive at a store.
