Denarius minted at Rome in 101 BCE by Gaius Fundanius, one of the tresviri monetales (mint officials) for that year. The coin celebrates the triumph of the consul Gaius Marius after his victories over the Germanic tribes of the Teutones and Cimbri at the battles of Aquae Sextiae and Vercellae, respectively--battles that helped restore Roman military prestige after a string of defeats and perhaps saved peninsular Italy from being overrun. On the obverse, the helmeted head of the goddess Roma. On the reverse, the triumphator Marius in his quadriga (four-horse chariot), accompanied by a youth who holds a laurel branch and rides one of the horses.
