10 Centavos seal type III

The Banco Nacional Ultramarino issued this note for circulation in Portuguese Guinea, one of the more isolated corners of the colonial currency network. Bradbury Wilkinson produced the printed base in London, but the seal type III designation marks a specific overprint or stamping applied to distinguish authorized emission batches — a practice BNU used across multiple territories to control re-issue without commissioning entirely new printing runs.

The 1914 date places this squarely in a period when colonial small-denomination notes were absorbing coin shortages driven by wartime metal demands in Europe. Ten centavos in fractional paper form was a pragmatic stopgap, not a planned instrument.
