This specimen is a very hefty cluster of intergrown, thick crystals of myriad habits, and on top sits this perfect, isolated "button" of a crystal! The crystal is SHARPLY tetrahexahedral with a dodecahedral modification, and measures almost 2 cm across. It just sits there looking at you, very bizarre to see at the top of this cluster! Ex. Weesleyan College and Neal Yedlin Collections. Comes with custom lucite display base.

A VERY dramatic piece, totally mesmerizing to me, with a medusa's crown of elongated SPINEL-TWINNED coppers leaping of a matrix of smaller crystals (all very sharp) ! This piece is 3-dimensional and looks good from ANY angle and any view. It is a mix of elegant atop a massive base, and the mix works. The piece is unique enough that, according to the Seaman Museum people who saw it, it is PROBABLY from this specific mine in the Keweenaw County heartland of copper mining. Comes with custom lucite display base.

This remarkable museum-sized specimen was the pride of the collection, and stands up there with the finest large copper specimens in any museum in the United States as a piece of US history. Even the Seaman Museum, our largest repository of historic and fine copper specimens, has not many pieces with such large cubic crystals and I think not another of this size for the style. This specimen has cubes all over it, a rare form in copper, to 2 cm. It has reticulated clusters of elongate, rectilinear crystals. It has distorted crystals of other habits. It has spinel twins tucked in the body. It is overall a riveting piece with so many different kinds of crystallization. Taking the size into account, as well, and you really do have a museum-grade, world-class copper. It was in a museum, in fact, for most of the 1900s - donated to Cranbrook at some point and then traded out by the late Neal Yedlin in the 1970s. I am told that this was the cornerstone of the Yedlin Collection, which was abosrbed into this collection on its purchase. Comes with a custom lucite display base. (probably Copper falls or Phoenix Mine),

This is the first of two extremely large and impressive "snakes" of intergrown copper crystals obtained by Gene Sensel from Werner Krauss' collection in 1962. Hauck bought the Sensel collection and kept these for himself. They are probably very old specimens, but there is no way to be sure how old or exactly which mine they came from. They are complete on both sides and all around; and are very hefty and impressive in person. For the size, this is an extremely elegant specimen too, with none of the uusual matrixy-ugly-included portions common in so many large coppers. This piece is the more elegant of the two by far, enough to me to make a 2-fold difference in value

This one is more massive and robust, and heavier, than its brother below. Its just not quite as elegant, but it IS very impressive and is in comprarison at a bargain price

Just a REALLY interesting and NATURAL , 3-dimensional piece of float copper! It looks carved, but is not. It is elegant, actually, for what it is, and has a surface polished smooth by natural tumbling in water in the past. weight 6.6 pounds = 3 kilos
ex. Richard Hauck
This piece is so exquisitely and minutely crystallized it looks like it was machine made, or made by a crazy kid with thousands of those little arts and crafts plastic ringlets. It LOOKS "woven," for lack of a better word. Just an extremely beautiful copper of substantially unique style, in a good size and price range!
ex. Richard Hauck
This is an incredibly ornate, intricate crystallized copper that looks like nothing so much as an ancient ceremonial shield. It features SHARP (razorsharp!) spinel-twinned copper crystals radiating off to either side of a central atrray of two larger and more robust crystals running lengthwise down the piece. Between each spinel twin "spoke" are hundreds of tiny conenctor crystals in a herringbone-style pattern, reinforcing the strength and stability of the whole piece as well as making for a mesmerizing look. The piece is 3-dimensional, in that it has a thick midsection lending stability and support. This is a VERY UNUSUAL STYLE for a Michigan copper and quite different than most of what you could obtain from these old mines. I have seen no other quite like this for sale, except for superficially similar material from the Champion Mine - in person, though, they are quite distinct.Comes with custom lucite display base.

Like other fissure vein pieces of substance, this most likely dates to the 1870s-1890s peak of production and has a wonderful old antqiue patina to it. This particular piece is a rarity - a thick cluster of intergrown spinel-twinned copper crystals , to 6 cm in length! While common enough from Arizona, such thick twinned clusters are NOT common at all from Michigan's historic mines. The crystallization is complete all around, and the piece is much more impressive in person because the camera blurs on the focus here. Also, the patina on this is a very desirable chocolatey brown! Comes with custom lucite display base.

This unusually massive skull weighs in at 12.8 pounds or over 5 kilos! It is unusually symmetric for such a large cast, and you can imagine Indians mining these and using them as natural bowls! This one is really quite special for the solidity , and mass, of the cast....usually they are much thinner (and hence large ones are prone to being cracked and ugly, not a beauty like we have here with no cracking and crevasses to mar it!)
ex. Cranbrook Institute ex. Neal Yedlin ex. Richard Hauck
This beautiful skull is nearly all complete, except for the hollow end to look in, has excellent form, and was exchanged out of the Cranbrook Institute by the intrepid Neal Yedline in March of 1975. For the size and pricepoint, i think its a GREAT example of this classic copper habit, unique to Michigan.
ex. Earl Calvert ex. Richard Hauck
An unusual piece, as it is a DOUBLE skull with one on each side, adhering together at a solid junction and showing clearly how these form in the cracks and spaces of a conglomerate lode around ball-shaped rocks. There is even a third mini-skull in the cluster. Overall this is thus very 3-dimensional and dramatic!
ex. Richard Hauck
A 3.1 pound, 1.5 kilo, really-well formed skull with extensions to one side. Quite a nice example!
ex. Richard Hauck
A large skull shaped somewhat like an open football, showing GREAT 3-dimensionality and even (this is rare) rudimentary crystallization at the edges! It is perhaps 70%-75% complete in its form, with the remainder probably just never forming to begin with as the edges here look naturally tapered as they should be. LARGE and impressive example of this habit!
