1/2 Tanga - Filipe I Goa mint

Philip I of Portugal — Philip II of Spain — came to the Iberian throne in 1580 following the death of the young King Sebastião at the Battle of Alcácer Quibir and the subsequent extinction of the Aviz male line. The Goa mint continued striking under the new Hapsburg king, though the transition introduced administrative friction between Lisbon and the Estado da India that left documentary records for this period fragmentary. The tanga itself was a denomination rooted in local Indian monetary convention, not Iberian — its subdivision logic answered to the bazaar, not to Lisbon's accounting.
