50 Centavos

Portuguese Guinea's 1933 coinage came years after most other Portuguese colonial territories had already received updated currency. The colony remained administratively peripheral — Lisbon's attention and resources were concentrated on Angola and Mozambique — and the 1933 issue reflects a catch-up effort rather than any deliberate monetary reform. Nickel brass was the practical choice for tropical colonial coinage, resisting corrosion better than cupro-nickel in the humid Guinea-Bissau coast.

These circulated hard in a cash-scarce economy where smaller denominations did most of the real transactional work.
