Ceitil - Afonso V Group 3 - Castle with towers formed by square elements, turrets with four battlements

The ceitil — named for Ceuta, the North African enclave seized by Portugal in 1415 — was struck specifically for colonial trade use, its low denomination suited to small transactions in territories where Portuguese commercial presence was expanding. Afonso V's reign saw sustained military engagement along the Moroccan coast, and the coin's design evolved through several die groups as production continued across multiple mints over decades. Group 3 is distinguished by the squared tower elements and four-battlement turrets, a detail that allows attribution to a specific production phase within the 1449–1457 window defined by Magro.
