Brass Bell found in Coal: Out-of-place Artifacts (OOPArt)
In a discovery in 1944 that by now is almost becoming common place, a man called Newton Anderson found this quaint brass bell inside a lump of coal that was mined near his house in West Virginia.
Newton dropped the lump and it broke revealing the bell encased inside. The bell underwent rigorous testing and was extensively analyzed at the University of Oklahoma and found to contain known metals but mixed together in an unusual blend and quite different from any modern alloys.
The bell is made of brass (an alloy of copper and zinc) with traces of tin, arsenic, iodine and selenium. It is about seven inches tall and is mounted with a crudely described figure appearing to have one visible leg, two arms and a head.
Numerous other such discoveries in coal have even been recorded, including the delicate gold chain mentioned previously and a cast iron pot that was also found inside a coal seam.
