1 Tanga - Filipe I Goa mint

Philip I of Portugal was simultaneously Philip II of Spain — the same monarch who had absorbed the Portuguese crown following the death of Sebastian I at the Battle of Alcácer Quibir in 1578, leaving no direct heir. Goa's mint continued operating under this union largely undisturbed, producing tangas that technically bore the name of a Spanish Habsburg king while circulating through a Portuguese colonial trading network stretching from Hormuz to Macau.

The tanga itself was a denomination rooted in local Indian monetary custom rather than Iberian tradition, adapted by the Portuguese to facilitate trade in a market where familiar units of account already existed.
