71/2 Reis '7=' - João VI Small armillary sphere - Goa mint

João VI issued this fraction specifically for Goa's local market, where smaller denominations were essential for petty trade that the larger milled coinage couldn't serve. The '7=' punch — a hand-stamped numeral applied to distinguish the value — was a practical fix for a colony operating on fragmentary monetary infrastructure, not a designed feature. Gomes records notable variation in the placement and depth of that punch across the series, a predictable consequence of manual application at the Goa mint rather than integration into the die itself.
