This is the most sculptural of the small lot of Keweenaw Peninsula silver and copper "half-breeds" that I purchased a couple of years ago. The silver is shaped like a boot or sock. It is also unusual, in that, there is far more silver than copper. Typically, there is more copper than silver.. Here, this hefty thumbnal nugget has more silver than copper. 2.0 x 1.8 x 0.3 cm
