An EXTREMELY RICH, old-time and sculptural silver-copper "halfbreed" from the famous Keweenaw Peninsula of Michigan. Most halfbreeds are less much less than 50% silver, but this hefty piece is at least 75% silver and weighs 52 grams. This fine piece was formally in the collection of George Robinson, currently curator of the Seamann Mineral Museum at Michigan Tech. 3.7 x 2.7 x 1.8 cm
