Gordian III Denarius

Marcus Antonius Gordianus was yet another third century emperor who assumed power during early adolescence. Deemed Pius, Gordian III became Augustus following the murders of the joint emperors.Balbinus and Pupienus by the Praetorian Guard, who then foisted the youth upon a willing Senate, which subsequently largely ruled in his name. Under the guidance of Timesitheus, a capable military officer whom the emperor had appointed as commander of the Praetorian Guard, Gordian III successfully campaigned against the Goths and the Persians. But Timesitheus took ill and died, and his successor, Philip, proved to be Gordian III's undoing, seizing the position of emperor for himself by first undermining Gordian III's authority and then engineering his assassination while both were still in far off Mesopotamia.

The coin's reverse depicts the emperor on horseback, RIC81 (RSC 234), supposedly is a rare type. This may not be the highest grade specimen, but it's still quite presentable, I think.
