That's what happened to a MI man.
Now, the space rock, dubbed Edmore meteorite, is waiting to find a permanent home.
University Geology Professor Mona Sirbescu first identified the piece as more than just a rock.
After the arrival of the unnamed owner, he pulled the rock out of his bag and she saw the biggest potential meteorite, which was about to examine.
The man learned about MI people finding and selling the meteorites and began to wonder how much his own rock was worth. The man, who has asked to remain anonymous, says that he knew the 10 kg rock came from outer space ever since he bought his house in 1988. However, she has never examined a rock that has turned out to be an official space rock, until now. Its composition, 88 per cent iron and 12 per cent nickel, proved it authentic, and an analysis at the Smithsonian verified the conclusion.
"It's the most valuable specimen I have ever held in my life, monetarily and scientifically", said one excited Sibescu.
Ms Sirbescu determined the specimen to be potentially worth $ 100,000 - that's approximately Rs 74 lakhs! The institution validated it to be a meteorite, mentioned the report.
The meteorite fell to Earth sometime in the 1930s. While touring the property, the man spotted the rock propping open a door and asked the farmer what it was.
The craziest bit? The old owner told the Grand Rapids man that, since the meteorite was a part of the property, it would now belong to him. The next morning the farmer and his father discovered the crater and dug out the meteorite, which was still quite warm. Sirbescu said. The Smithsonian has named the rock Edmore meteorite and is considering buying the meteorite so it will be displayed later.
Sirbescu further added that "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". The Smithsonian Institution, as well as a mineral museum in ME, is considering to buy this one for displaying it, informed CMU.
