100 Dollars De LaRue Calibration Note

De La Rue calibration notes are internal production tools, not currency — printed to verify ink density, registration accuracy, and press alignment before a live banknote run begins. They are discarded as a matter of routine, which is precisely why they surface so rarely in collector hands. This example follows the familiar "100 Dollars" denomination format that TDLR has used across multiple calibration series, chosen because it mimics the physical demands of a high-value note without referencing any specific client country.

Acquisition almost always traces back to De La Rue employees or press-room waste intercepted before destruction.
