Example of PYRITE DOLLAR (PYRITE SUN) in the Rock Professor


Formed in the seams between black shale and coal  300,000,000 years ago, these pyrite dollars do not appear to be fossils, but an aggregate of tiny pyrite crystals. 

Today, they are collected by coal miners in Randolph County, Illinois.  As the Illinois coal mines are shut down one by one, these specimens will become more and more rare.
