NEW YORK (AP) — A very special document will be auctioned off later this year — a rare copy of the U.S. Constitution. Sotheby’s announced Friday — appropriately on Constitution Day — that in November it will put up for auction one of just 11 surviving copies of the Constitution from the official first printing produced for the delegates to the Constitutional Convention and for the Continental Congress. It’s the only copy that remains in private hands and has an estimate of $15 million-$20 million. The copy of the Constitution is on public view at Sotheby’s York Avenue galleries until Sept. 19 and then travels.
