José I's copper coinage for Goa was struck during a period when the Estado da India was operating under severe fiscal strain — the 1755 Lisbon earthquake had devastated the metropolitan treasury, and Pombal's subsequent reforms disrupted colonial monetary supply chains for years. The Goa mint filled the gap with locally produced copper for small transactions, though quality control was inconsistent and planchet preparation notoriously irregular across the 1760–1762 run.
The short production window makes date-specific attribution difficult; most examples are assigned the range rather than a single year.
