A rare copy of the U.S. Constitution that was printed shortly after the Constitutional Convention in 1787 and played a role in the document’s adoption by the original 13 states sold for more than $11 million during a live auction Thursday evening.

The high bid, from a buyer whose identity was not disclosed, was $9 million. That does not include the buyer’s premium of 23% or the taxes.

The sale was handled by Brunk Auctions, which is based in Asheville, North Carolina. Bidding began at $1.1 million but quickly jumped to $5 million. It took just over seven minutes before the bidding closed at $9 million, said Nancy Zander, director of external affairs for Brunk Auctions.

“It was a spectacular price,” Zander said Friday night.

The copy of the Constitution was found two years ago in a filing cabinet in the house at Hayes, a farm once owned by Samuel Johnston, who served as governor of North Carolina from December 1787 to December 1789. — The New York Times
