Calibration notes of this type were produced by De La Rue for internal press registration and color-matching purposes — not for any issuing authority. They circulate among collectors precisely because they were never meant to leave the factory. The $20 denomination and format mimic a generic anglophone banknote convincingly enough to serve their technical purpose without referencing any real currency.
De La Rue has printed currency for well over a hundred governments since the nineteenth century, and these test pieces occasionally surfaced through employee channels or were sold off in bulk after machinery upgrades made specific calibration runs obsolete.
