2 pretty simple questions. First on this bill (88' series A one dollar) where the Plate Serial Number would normally be it just has a small "4" is this correct. Second question is what I really am inquiring about. On the reverse off to the right of the "In God We Trust" it looks as if there is a small green number "8" printed on. It seems a bit out of place to me and not like other bills I have seen. Is this correct? I have taken a very cruddy cell phone picture that shows the location, but it can not show the figure itself.
