Ti. Veturius T.f. Gracchi. 137 B.C. AR denarius (19 mm, 3.96 g). Rome. TI · VET, helmeted and draped bust of Mars right; behind, X / ROMA above, youth kneeling left, looking right, between two warriors, each holding a spear, who touch with their swords a pig which the youth holds. Crawford 234/1; Sydenham 527; Veturia 1.
This piece was minted circa 137 BC, under the authority of the moneyer Ti. Veturius. The obverse type depicts the bust of Mars facing right, with X and legends TI.VET. behind. The reverse type features youth kneeling left between two warriors who are touching with their swords a pig that he holds. The legend ROMA appears above. This gens was one of the most ancient of Rome, it was patrician and plebian, and is said to have been of Sabine origin. The reverse type represents the mode of taking an oath amongst the inhabitants of the Italian states, and may refer to an ancestor who took an active part in the close of the Third Samnite War in 290 BC. The highly original designs of the coinage of the moneyer Tiberius Veturius have occasioned much scholarly comment. The depiction of an oath-taking scene on the denarius recalls the initial issue of Roman gold in the early stages of the Second Punic War. It may refer to the treaty of Caudium concluded with the Samnites in 321 BC following the disaster at the Caudine Forks. A Roman army was ambushed by the Samnites in a mountain pass and forced to capitulate. One of the consuls who negotiated this treaty was an ancestor of the moneyer, T. Veturius Calvinus. Crawford's dating of this issue is substantially earlier than that of Grueber (93-92 BC) and Sydenham (110-108 BC). The type was later revived during the Social War by the Samnite leader C. Paapius Mutilus. (Cited from: https://www.cointalk.com/threads/ti-veturius-ar-denarius-with-oath-taking-scene.222598/)
