Eleven rare and historic naval flags brought a total of $784,500 at a Freeman's auction in Philadelphia, according to reports.

Banners that flew over the course of two centuries from the USS Constitution, dubbed "Old Ironsides" for its battle toughness, were sold along with a cannonball from the storied warship.

Late collector H. Richard Dietrich Jr. assembled the offered collection of 12 flags; one did not sell.
