Hello: My name is Mike and I'm one of the owners of M and M Gold Exchange. We specialize in buying large lots from pawn shops, jewelry stores and gold buyers. M and M Gold Exchange does not use high costing retail centers to conduct our business so we have the ability to pay higher prices than any other precious metal dealers.
