[ES] This is a historical/numismatic study of 10 18th century feluses (fulus) found during recent archaeological interventions or by chance in the city of Algeciras, the first Arabo-Islamic foundation in the Iberian Peninsula. The importance of this work is due to the place where the findings were made and their geographical concentration — the urban centre of Algecirca — and the scarcity of these so-called ‘conquest coins’. These Algecireans’ feluses had to arrive in the city at the beginning of the eighteenth century with the first Arabic/Bertwerp quotas landed in its port between J.C. 711 Y 712 or, in some cases, before the Conquista itself.
