15 Réis - Maria II Countermarked over '15 Réis'

Portugal's Goa mint had long struggled to maintain a coherent copper currency in its Indian territories, and by mid-century the solution was simply to restrike existing stock rather than produce fresh blanks. These countermarked pieces — old 15 Réis coins punched again with a new 15 Réis mark — were a fiscal stopgap during Maria II's reign, a queen whose government was simultaneously managing the aftermath of the Liberal Wars and chronic colonial monetary disorder. The double-denomination countermark creates attribution headaches that Gomes and KM don't fully resolve between them.
