Item Description

A hefty 84-gram nugget of copper, with rare mixed silver nugget enclosed within. These are called "halfbreeds", historically. Although both are metals and occur freely in these mines, seldom do they mix into such nuggets. Halfbreeds with such attractive zoning as this are considered desirable.
