Seymchan
  
Seymchan was found in Russia by geologist F. A. Mednikov while conducting a survey of the area.  A mass of 272 kg was discovered in June 1967 and a second specimen was found in October.  Subsequent expeditions have yielded additional specimens of pallasitic content.

Seymchan is a pallasite, but it is considered anomalous due to its high iron content. Before the discovery of its pallasitic structure it had been classified as IIE anmalous coarse octahedrite. Seymchan is stable and rust-resistant.

Beautiful 582 gram polished sphere.  It is 60 mm in diameter.  Making a sphere causes a lot of cut loss and labor, making them rarely offered for sale in pallasitic meteorites.  The dark area in the center of each photograph is caused by my reflection in the highly polished surface - $4000-
