This label, dated 1835, is the same year the species was formally described to science! I cnanot but find it interesting that this dates so far back. The original label name was "Schriftenz" if I read it right, with a note to the side that it "looked like krennerite" added later (as that species was only identified in 1877) in a different pen. In any case, its a very rich, and attractive, specimen of sylvanite with good size, coverage, and excellent crystals for this, the type locality.
