Specimen banknotes were created to mark the release of a new note issue and were typically kept for museum and banking archival purposes and, occasionally, presented to highly influential figures. They often came onto the market after their interest by collectors was realized by their owners or those who inherited one. Because of the high value of £100, this note was printed without a serial number, perforated with multiple holes, and ink stamped with the word "SPECIMEN" to prevent its use in circulation.
