Thanks for the information and the link. When held up to a light I can see what looks like a security thread on the right half of the note and a lion head watermark in the circle area on the left. The 3b notes have the red seal to the right of the signature but for some reason the seals are so faded that they didn't show in the pictures. Could these be attempts at removing the seal? Although some are more faded than others all of the seals can be seen in hand. Any idea on value?
