备注	Nigeria's shift to polymer for this commemorative issue was part of a broader push by the Central Bank to reduce counterfeiting and extend note lifespan in a climate that routinely destroys paper currency within months. The 50th independence anniversary timing — October 1960 to October 2010 — gave political cover for the format change, though the underlying motive was operational. Nigerian Security Printing and Minting in Abuja handling the print run is notable: earlier polymer issues in the series had required overseas production capacity. Printing domestically on polymer substrate by 2010 reflected a decade of serious investment in the Abuja facility.
