5 Avos Banco Nacional Ultramarino

The Banco Nacional Ultramarino was Lisbon's instrument of colonial monetary control across multiple territories simultaneously — the same institution issued notes for Portuguese Guinea, Cape Verde, São Tomé, Mozambique, Angola, and Timor, often using closely related plate designs adapted by territory. This 5 Avos for Timor sits at the very bottom of a denomination structure designed for a subsistence economy where fractional values actually mattered in daily commerce.

Bradbury Wilkinson's involvement is worth noting — the New Malden firm handled security printing for dozens of colonial and minor-state issuers through the mid-twentieth century, and their intaglio work on low-denomination colonial notes was rarely given the attention reserved for flagship issues.
