1 Real - Sebastião I Goa mint

Sebastião I was thirteen years old when these coins were struck at Goa, his reign having begun in 1557 under regency governance. Portuguese India's copper coinage of this period was produced primarily to serve local market transactions that silver and gold could not practically reach, and Goa's mint was operating under persistent logistical pressure — copper supplies to Estado da India depended on irregular shipping from Lisbon and whatever could be sourced through local trade networks. The young king would go on to die at Alcácer Quibir in 1578, triggering a succession crisis that ultimately delivered Portugal into Spanish hands under Philip II.
