Copy of US Constitution found in filing cabinet sells for $9m

A rare 237-year-old copy of the US Constitution has been sold at auction for a whopping $9m (£7m).

The document was discovered in a historic building in North Carolina in 2022, inside a dusty old filing cabinet. 

The copy was printed in 1787 after delegates from the colonial states met for the Constitutional Convention and drafted what would become the founding document of the US federal government. 

There are believed to be only eight copies like this one left in existence, and seven of them are publicly owned.
