This paper aims to investigate the monetary circulation during the Late Roman Empire and Late Antiquity in the city of Dertosa. To do that, we reviewed a large number of coin finds from the archaeological site close to the cathedral. The excavation uncovered significant remains in a high-status sector next to the walls, with evidence of great activity between the 4th and the 8th centuries. This analysis has allowed us to study an important number of imitations of official Roman currency and some little hoards, one of them made up of halved coins. Other important finds include two Visigothic tremisses, Vandal, Late Roman and Byzantine bronzes from Northern Africa and Eastern Mediterranean, furnishing remarkable information about the monetary circulation in this area of Ebro River mouth.
