Since paper notes were issued so seldom, people had to make do with them for many years. N.C. notes have often been sewn together, backed with other paper, and/or pinned (with what are now antique pins.)
To be issued each note was hand signed on the front by prominent people. North Carolinians in particular had the habit of signing each note on the back as they spent it, like endorsing a check today. This leaves a record of who was living (and spending) there in the mid-1700’s. Signatures are all in the brown ink of the era.
Forty Shillings was the highest denomination of the 1754 issue, and had the fewest notes made (2,500).
