Denarius serratus L. Licinius Crassus, Cn. Domitius Ahenobarbus and C. Malleolus

Struck by a traveling mint accompanying the Roman colonial commission sent to found Narbo Martius — modern Narbonne — in 118 BC, this is one of the few Republican issues directly tied to a specific act of territorial expansion rather than minted at Rome itself. The colony at Narbo, Rome's first in Transalpine Gaul, was controversial enough that its opponents in the Senate tried to block it; the bill was pushed through by Crassus and Ahenobarbus over substantial opposition.

The serrated edge — the flan notched before striking — appears across multiple issues of this period and is generally thought to have been a device against plating fraud, though it added significant production cost.
