| 背面描述 | Bold cross of the Order of Christ (Cruz da Ordem de Cristo) occupying the central field, with the four quadrants each bearing the mint mark PP (for Porto), the four initials placed in the angles of the cross so as to read PPPP at the corners. The date appears within the circular Latin legend, which carries the Constantinian motto. The rim features a continuous milled border matching the obverse. |

The Porto mint operated under royal license as a secondary facility to Lisbon, activated during periods when colonial gold from Brazil arrived faster than a single mint could process it. João V's reign coincided with the peak of Minas Gerais production — by 1712, Brazilian gold was flooding Lisbon in quantities that genuinely overwhelmed the Casa da Moeda's capacity. The Porto facility struck this type across a narrow window before consolidation rendered it redundant.
Gomes distinguishes two varieties within this type, J5 100 and J5 101, differentiated by subtle die characteristics that reward careful examination under magnification. Porto mint gold consistently shows slightly rougher edge treatment than contemporary Lisbon issues.
