The man even let his kids take the rock to school for show-and-tell throughout the years.
A man has discovered that a rock he's been using as a doorstop for 30 years is a meteorite worth $100,000.
He was content to use it for propping the barn door open the last 30 years, until MI residents began selling much smaller meteorite bits that were sprinkled across the state when a meteor blazed through the sky in January, he told the university.
The man said that he was able to discover the meteorite's origins, noting that he'd spoken with the farmer who'd originally discovered the space rock in the 1930s.
Central Michigan University says Thursday that the 22.5-pound space rock was recently identified by Department of Earth and Atmospheric Sciences professor Dr. Monaliza Sirbescu after the owner "brought it to her out of curiosity". Upon purchasing it, he noticed a large rock holding the door open, according to Central Michigan University.
Then, "I said, wait a minute".
This is where geologist Mona Sirbescu of Central Michigan University in Mount Pleasant enters the story. The iron and nickel meteorite is the sixth largest meteorite found in Michigan, according to the Smithsonian Museum and Central Michigan University.
Siberscu still wanted a second opinion and sent off a slice of the rock to the Smithsonian Institution.
"I could tell right away that this was something special", she said.
"It's the most valuable specimen I have ever held in my life, monetarily and scientifically", Sibescu added, noting that the meteorite is composed of of 88.5 percent iron and 11.5 percent nickel.
The man said that the original farmer said he heard the meteorite come crashing down, "and it made a heck of a noise when it hit". A museum in ME is also interested.
A rock that was used as a doorstop on a MI farm for decades has been identified as a meteorite worth $100,000.
The meteorite's owner said that regardless of the buyer, he will donate 10 percent of the sale amount to the university.
