Peter Huntoon also has a book titled "U.S. Large size National Notes" as well as another volume covering Territorial National Notes, if your's are older than the state and go back into the Territories era.
Maurice Burgett; Steven Whitfield wrote a pamphlet guide/reference book on Oklahoma Territorials in 1980.
