This mine was founded in 1837 and mined continuously at peak production through the US Civil War, reaching its heyday by 1900 although it remained open until 1953. Here we have a historic, significant, and luckily gorgeous specimen of the botryoidal variety of chalcopyrite called "blister copper" by the miners. It is the finest such example I have seen for sale on the market, outside of the museum collections on the East Coast. It is colorful, 3-dimensional, and large. It is also complete all around. As they are heavy and ore-rich, and were not thought as collectible at the time as the sharp chalcocites from this old mining locality, ironically fewer specimens probably survive today. At least, I see them even less on the market than the equally historic chalcocites, so this is my assumption as to why. NOTE: THE HANDWRITTEN LABEL IS FROM WILLIAM SANSOM VAUX!
