50 Centavos

The Banco Nacional Ultramarino, chartered in Lisbon in 1864, held note-issuing rights across Portugal's overseas territories and issued fractional notes like this 50 Centavos during the post-WWI inflationary period, when coin shortages made small-denomination paper a practical necessity throughout the Portuguese colonial system. The precise territory of issue for Pick 53 warrants attention — BNU issued near-identical fractional notes simultaneously across multiple colonies, and misattribution between Portuguese Guinea, Mozambique, and Angola series is a recurring cataloging problem.
