备注	Banco Nacional Ultramarino's wartime fractional issues for Portuguese Angola emerged from a practical crisis: the near-total disappearance of silver coinage from circulation after 1914, a problem common across colonial Africa as metal was hoarded and diverted to Europe. The seal type classification — I, II, and III — distinguishes successive overprint or authentication variants applied to what was essentially the same printed stock, a field detail that matters considerably for accurate attribution since the types are frequently conflated in older references. Bradbury Wilkinson produced the base notes in London. The type III seal is the scarcest of the three variants.
