A rare copy of the US Constitution went missing for centuries. Now it's being auctioned for millions

A rare copy of the U.S. Constitution that was signed and sent to states to ratify is up for auction later this month in North Carolina. The document was found inside a filing cabinet at a property once owned by a former North Carolina governor. The copy was made after the Congress under the Articles of Confederation approved the new Constitution in 1787. Secretary Charles Thomson signed two copies for each of the 13 states and sent them away. Only eight are known to still exist and the copy being sold Sept. 28 by Brunk Auctions in Asheville is the only known privately held copy.
