As

Iltirta was an Iberian city in the northeastern peninsula, roughly corresponding to modern Lleida, and its bronze coinage was struck under the broad umbrella of Roman Republican influence following the Second Punic War — Rome having wrested the region from Carthaginian control after 206 BC. The city retained enough administrative autonomy to issue its own fractional bronze well into the mid-second century, a privilege Rome extended selectively across Hispania Citerior as a tool of economic integration rather than pure conquest.

The as denomination placed this squarely in circulation alongside Roman-allied issues, facilitating local market exchange in the Ebro valley.
