Rock used as doorstop is actually a meteorite worth $100K

"For 18 years, the answer has been categorically "no" - meteor wrongs, not meteorites", she said.

"I could tell right away that this was something special", Sirbescu said Wednesday in a statement.

The Smithsonian Institution in Washington, D.C., corroborated Sirbescu's analysis that the 22-pound "rock" is, indeed, a meteorite, and is apparently the sixth-largest of its type to be discovered in MI.

"It's the most valuable specimen I have ever held in my life, monetarily and scientifically", Sibescu said.

She found that it was an iron-nickel meteorite with about 88 per cent iron and 12 per cent nickel, a metal rarely found on Earth.

"What typically happens with these at this point is that meteorites can either be sold and shown in a museum or sold to collectors and sellers looking to make a profit", Sirbescu said.

David says the man who sold him the barn described the awesome tale of the meteorite making an impact crater in the backyard.

This rock might be worth as much as The Rock. The then owner told the man it was part of the property, and he could keep it.

It's the doorstop that's been used to prop open a MI man's barn door for the last 30 years. This is the rags-to-riches story of a rock from outer space.

The meteorite weights 22.5 pounds and fell from the sky in 1930's. So in February, he took the meteorite to Central Michigan University to have a scientist look at it.

The Smithsonian Institution is considering purchasing the meteorite, Central Michigan University said. The farmer told Mazurek that he and his father watched the chunk of rock slam into their property one night and picked it up the next day, when it was still warm to the touch.

An additional sample was sent to John Wasson, professor emeritus in the Earth, Planetary and Space Sciences department at the University of California, Los Angeles, who will conduct a neutron activation analysis to determine the full chemical composition of the meteorite and potentially reveal rare elements that could increase its value. Whatever amount he winds up donating, Sirbescu said her students, the university and herself have already been beneficiaries of the find.
