Ceitil - Afonso V Group 7 - Long and low outside wall, whose ends touch or cut the circumference, Shield of the 4th type

The ceitil was introduced under Afonso V specifically to facilitate trade along the North African coast — Ceuta, conquered by Portugal in 1415, gave the coin its name. These were the lowest denomination in circulation, struck for petty transactions and rapidly worn in use. The Group 7 classification under Magro's typology identifies a specific die treatment of the outer wall, a detail that only became systematically catalogued in the late twentieth century as collectors began distinguishing what earlier references lumped together.

Copper survivorship from this reign is poor. The 1458–1460 window sits within Afonso's active Moroccan campaign period, when mint resources were under pressure.
