This large copper-silver "halfbreed" is from the world renowned, but long depleted, copper deposit in the Upper Peninsula of Michigan. The specimen is a slightly rounded nugget with good eye appeal. With the unusual silver knob atop, it is a very compelling specimen and unusual in the richness of both metals without showing intermixing. Over 9 ounces, or 265 grams! 8.3 x 4.6 x 2 cm
