Cruzado - Afonso V Lisboa mint

Afonso V's cruzado was introduced as part of a deliberate monetary reform designed to produce a gold coin capable of competing in Mediterranean and Atlantic trade circuits, where Portuguese merchants increasingly needed a reliable high-purity specie. The timing coincides directly with Portugal's aggressive push down the West African coast — Elmina was still decades away, but gold from sub-Saharan trade routes was already flowing north through Arguim, and the crown needed a coin worthy of that commerce.

The Lisboa mint attribution distinguishes this from later Porto-struck pieces in the series. Gomes A5 31 is among the more frequently encountered references in the type, though condition varies sharply given the coin's active commercial use across two continents.
