CMU professor confirms Michigan's 6th largest meteorite found in Montcalm County

Rock used as doorstop for decades identified as $100K meteorite

Meteorite used as doorstop for decades worth $100,000

A man in MI discovered that the big hunk of malformed rock that was once propped open a door on a farm he bought is actually worth as much as $100,000. The man asked about the large, odd-looking rock that was holding the door open. He contacted Central Michigan University who tested and confirmed that the rock was not only a meteorite, but a particularly large one at that.

Central Michigan University CMU geology faculty member Mona Sirbescu holds the 22.5 pound meteorite used as a doorstop for decades.

The farmer told him it was a meteorite, that it was part of the property and he could have it.

He kept it for 30 years - also using it as a doorstop and sending it to school with his children for show and tell.

"I walked in there and there's this rock and i said you got everything all cleaned up but what's this? and he said oh that's a meteorite", says David, who owns the meteorite. He and his father dug it out the next morning and it was still warm. Weighing 22 pounds, it's the sixth-largest recorded find in MI - and potentially worth $100,000, according to CMU.

This year, the man was inspired by stories of MI residents finding and selling pieces of meteorites. "I wonder how much mine is worth'".

It has been named the "Edmore" meteorite after the town in which the farm is located.

Upon receiving the meteorite, Sirbescu evaluated it and discovered it was an iron-nickel meteorite, composed of 8 to 8.5 percent iron and 11.5 percent nickel.

The Smithsonian is considering purchasing the meteorite for display. He is considered the guru of iron meteorites, Sirbescu said, and is doing a neutron activation analysis to determine its chemical composition.

Throughout her tenure, Sirbescu has frequently been asked to examine specimens of alleged space rocks, to see if they were worth any money. A mineral museum in ME is also looking into it.

The owner has promised to donate 10 percent of the sale value to the university. So, he took the rock in to Central Michigan University for testing.
