A US classic a choice Halfbreed of Silver and Copper that shows perfectly the two metallic colors with very bright luster. Looks fine on all sides, the Halfbreed masses from this region are unlike anything from other places. The copper mined in the Upper Pennisula of Michigan tended to have some small percentage of Silver mixed in. This was especially desirable in the early manufacturing of electrical wires.
