4 Tangas - Filipe III Goa mint, xx4x

Philip III of Portugal (Philip IV of Spain) never visited Goa, yet his monetary policy there was administered through a mint that operated with considerable autonomy from Lisbon — routinely striking coins years after the official authorization date, which explains the ambiguity in the "xx4x" date format used in cataloging this type. The Goa mint in the 1630s was producing silver under increasing pressure from VOC competition in the Indian Ocean trade network, where Portuguese commercial dominance had already begun its structural decline.

Gomes F3 26 places this squarely within the second Goa tanga series under Philip III, struck to a standard calibrated for local bazaar transactions rather than intercontinental bullion exchange.
