"For 18 years, the answer has been categorically 'no, '" she said.
A rock (pictured) that was used as a door stop for three decades has turned out to be a meteorite worth $100,000 (£76,000). He says the meteorite came with the barn he bought in Edmore back in 1988.
An examination found that the rock is an iron-nickel meteorite composed of mostly iron with 12 percent nickel.
He asked the then-homeowner about it who told him it was a meteorite which the farmer had discovered on the property in the 1930s.
Now, the Smithsonian Institution is considering making an offer on the space rock. 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.
"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.
Thousands of meteorites hit the earth each year, but most go unnoticed because they land in the ocean, or away from cities and towns.
"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.
The owner thought little of it and kept it as a door stop, until recently when he made a decision to find out how much his odd rock was worth. She said it will likely be called the "Edmore meteorite". A colleague there further analyzed the sample, including with an acid test to reveal the Widmanstätten pattern, a property of most iron-nickel meteorites that can not be faked.
A sample has been sent to John Wasson, professor emeritus in the earth, planetary and space sciences department at the University of California, Los Angeles.
