American Hundred Dollar Bills Without A Seal

A coin dealer in Delaware discovered a fault on some one hundred dollar bills. The serial numbers and seal on the bottom are missing. They're not counterfeit. It's real money with a misprint, and one dealer is paying $400 for the misprinted hundreds.
Some believe the bills may have been stolen from the presses and cut by hand but the United States Bureau of Engraving and Printing says it has no reports of missing money.
