The specimens offered were collected at Michigan's Keweenaw Peninsula known as the most important locality in the world for pure native copper. The purity standard for refined copper is compared to Keweenaw copper. Pre-historic people minded copper from these mineral rich veins for centuries before the advent of commercial mining which began in 1845. Copper is said to be the metal of the god Hermes, who facilitates mental agility and quick wit. It is a conductor of electricity and is used in many manners of healing including the treatment of arthritis.
