"For 18 years, the answer has been categorically "no" - meteor-wrongs, not meteorites", Sibescu said in a Thursday statement, according to CNN.
The man named David, who didn't want his last name used says the rock has been used as a doorstop in a barn for decades. Most iron meteorites are generally comprised of anywhere between 90 and 95 percent iron, with the rest made up nickel, iridium, gallium and occasionally gold. This is the rags-to-riches story of a rock from outer space.
Weighing 22 pounds, it's also the sixth-largest recorded find in MI - and is believed to be worth $100,000, according to CMU.
"It's the most valuable specimen I have ever held in my life, monetarily and scientifically", Sibescu said.
Siberscu still wanted a second opinion and sent off a slice of the rock to the Smithsonian Institution.
Almost three dozen years, the space stone was in Edmore, and then to Grand rapids, where he moved the new owner.
He then kept the meteorite with him for the next years, and even allowed his children to bring it to school for show and tell.
It's a story that began out of this world almost a hundred years ago when a meteorite crashed down to earth near Edmore, Michigan.
The Smithsonian Institution and a mineral museum in ME are now looking into purchasing the meteorite for display.
Now, the space rock, dubbed Edmore meteorite, is waiting to find a permanent home.
"Just think, what I was holding is a piece of the early solar system that literally fell into our hands", Sirbescu said of the meteorite.
But he's not hoarding the payday, because 10% of the rock's value is already pledged to CMU's earth and atmospheric science students.
The meteorite hasn't sold yet, but the Smithsonian Museum is considering buying it, as well as another collector.
