This fine, old silver appears to be a floater, with no visible points of attachment. It is composed of several exquisitely crystallized, dendritic, branching wires which culminate in crystals to 1.1 cm in length. The location, the historic Cliff Mine, was Americas first major copper mine, dating to the 1840s. Silvers of this caliber are exceedingly scarce today, and tend to come out of museum collections and a few major private stashes only at this point.
