The ceitil was introduced specifically to facilitate trade with Ceuta — the North African enclave taken from the Marinids in 1415 — and its name almost certainly derives from the city itself. These coins circulated heavily in the port economy, passed between sailors, dockworkers, and merchants for whom a fractional copper piece was a practical daily necessity. Group 6 is distinguished by its square-element tower construction and battlementless towers, a die characteristic that places it within a narrow production window of roughly two years during Afonso V's reign.
