| Reverse description | A large plain cross pattée occupies the central field, set within an inner beaded circle. At the centre of the cross is a crowned royal cipher or ornamental knot. The letter P appears in two quadrants of the cross, indicating a mint initial. The surrounding legend VINCES·IN·HOC·SIGNO, accompanied by the mark PPPP, runs around the outer beaded border, the whole composition being typical of the hammered tostão coinage restruck for Brazilian colonial circulation. |

| Additional information |
Following Portugal's restoration of independence from Spain in 1640, the new Braganza regime faced chronic silver shortages in Brazil and lacked the infrastructure to strike fresh colonial coinage quickly. The solution was brutal in its pragmatism: existing Spanish colonial reales and worn Portuguese tostões were countermarked and revalued, forcing currency into circulation by royal decree rather than by minting it. João IV's 1663 countermark program was among several such emergency measures applied to whatever silver was already in Brazilian hands.
The wide weight range on surviving examples reflects exactly this — the host coins are not uniform, and authentication hinges on the countermark punch itself rather than the planchet.
