Vespasian worked hard to establish his sons as the heirs to the throne. Even before he was emperor, Titus appeared on Roman Coinage. The front is a bust of Titus with the legend T CAES VESPASIAN IMP PON TR POT COS. This is his formal name and a list of his titles including Caesar, Tribune, and Consul. The reverse is Victory holding a shield, propped up against a palm tree. Titus served as his father’s right hand man and was very loyal to him. He served as the commander of the Praetorian Guard and was able to uncover a plot to overthrow Vespasian in 79 AD. Titus became emperor immediately after Vespasian’s death in 79 AD. Titus was the first Roman emperor to succeed his biological father. This can be seen in the resemblance between the images of Titus and Vespasian on coins.
