Those are really nice and...
... the fact that you knew the cashier who signed them make them even more special. Notes like that have no book value. There were a lot of notes through history that were hand signed and even with the smaller quantities in circulation the number was still large enough that hand signing seemed and impossible task. Why did you cut them all in half?
(I figured it was your scanner).
Thanks for sharing those! They sure look fresh and crisp too like they just came out of the cash drawer!.
