20 Centavos

Angola was under Portuguese colonial administration when this coin was issued, and its production coincided with a period of severe monetary instability in the metropole — Portugal itself was running substantial war debts from World War I and struggling to stabilize the escudo. Colonial coinage was a separate administrative headache, issued through the Junta da Moeda in Lisbon for circulation in Portuguese West Africa rather than struck locally. The two-year span of this issue likely reflects interrupted supply chains rather than a planned series change.
