This is an old specimen from the Erling Collection with an old University of Chicago label. This is possibly rathite and there is a question mark after baumhauerite. Whatever the case it's a very rare sulfosalt with spheroidal like crystals donated to U of Chicago in 1939
Origin: Cerro de Pasco, Peru
