Semis L SEMP MAX M CAEC AED

Celsa — modern Velilla de Ebro in Aragon — was a Roman colony established in the Ebro valley following Caesar's campaigns in Hispania, and its earliest colonial coinage reflects the administrative machinery being built almost in real time. The magistrates named on this issue, L. Sempronius Maximus and M. Caecilius, served as aediles responsible for overseeing local markets, weights, and public buildings — precisely the civic functions that justified issuing small bronze fractions in the first place.

The dating window places this squarely in the turbulent decades of the late Roman Republic, when colonial mints across Hispania were asserting local identity through bronze issues that Rome itself had no interest in producing centrally.
