OKH-598 Pyrite Hannibal, Missouri. Paul and Dawne Dunning Collection. This is a typical floater composed of cubes modified by octahedrons. What is atypical about the specimen is its small size. He measures 2.4 x 2.4 x 1.6 cm so was an excellent thumbnail sized piece. High luster and no damage. $30

OKH-595 Calcite and Pyrite Brushy Creek Mine, Missouri. Paul and Dawne Dunning Collection. Nicely formed miniature measuring 4.5 x 2.5 x 1.6 cm. Great luster ranging from moderate to high depending on the face. Attractive overgrowths of pyrite add the expected contrast for which these specimens are so famous. Calcite is gray but very gemmy on close inspection. You can see right down to internal pyrite phantoms in some places. Zero damage. Excellent quality for this more common material. $35

OKF-373 Pyrite Bar St. Joe Lead District, Missouri. Ex Anthony P. Dunn collection. Now here is a really serious specimen for the collector of classic American minerals. This specimen measures 13.5 cm in length it is 6.7 cm wide and its base. It averages approximately 4 cm in thickness and is fully terminated on all sides including its base. There is a single minor white dolomite crystal which is the only accessory mineral present. The bar is very stable standing on end for display and is slightly curved in form. I can't say enough about this piece’s rarity and aesthetics. It is one of those amazing pieces which is seldom seen in the mineral market especially in large damage free pieces like this. There is another collection number on the base of the piece but my guess is that this specimen was mined in the mid-1970s. They don't get much better than this so I suspect this one should go fast even though it's an expensive piece of pyrite. Comes with a custom engraved acrylic base. $1600
