Test Note De La Rue Systems Ltd

De La Rue produced test notes — sometimes called "specimen blanks" or house specimens — primarily for internal quality control, sales demonstrations, and calibration of currency-handling machinery. This example would have been used to test sorting, counting, or authentication equipment without committing actual security-printed currency to the process. They were never intended for circulation and carry no legal tender status anywhere.

Cotton substrate on a test note is deliberate: machine manufacturers and bank procurement officers needed material that behaved identically to real currency stock during trials.
