The Copper with Silver specimens from Michigan are not very usual. The Keweenaw Peninsula is one of the few localities in the world known for producing spectacularly copper and silver specimens. This one is a slightly rounded copper mass with a knob of Silver on the top. This specimen would make a valuable addition to any mineral collection as a rare and exceptional example of two native metals together in one specimen. No damage.
