Half-breeds" of silver and copper are highly prized by collectors. This is a 91-gram nugget of solid silver and copper. The silver you can see as the three large light-colored spots set in the copper. You sometimes see this half-breed phenomenon in crystallized specimens from Michigan - not as often nuggets. From the collection of noted California collector Charles Hansen.
