Tanga - Afonso VI Diu mint

Afonso VI's reign was effectively a regency under the Count of Castelo Melhor, and Portuguese India by 1661 was a shadow of its former commercial dominance — Diu itself had survived a second Ottoman siege decades earlier but was increasingly isolated as Dutch and English competition strangled Estado da India trade routes. Coinage from the Diu mint in this period was produced in modest quantities to serve a contracting local economy, and survivors attributable specifically to this mint are meaningfully scarcer than Goa issues of the same type.
