Accounts by surviving literary sources concerning Regalianus are brief and few in number, and are mostly considered unreliable.
Regalianus was married to Sulpicia Dryantilla, a woman from a prestigious senatorial family, which instead points to Regalianus being of high-ranking Roman descent.
Unlike Ingenuus, and revolutionary for an imperial claimant, Regalianus founded his own mint at Carnuntum, his seat of power.
Regalianus minted coins of himself and his wife, though they were typically of poor quality.
Regalianus was proclaimed emperor either late in 260 or in 261, and his claim to imperial power ended with his defeat and death after several months, either in 260 or 261.
Unlike Ingenuus before him, Regalianus minted his own coins at a mint he himself established at Carnuntum, a revolutionary move for an imperial claimant.
Most, but not all, of Regalianus' coins have the formula AUGG.
All of Regalianus' coins were minted at Carnuntum, and they are all overstruck issues, struck on coins minted by earlier emperors of the third century, such as Septimius Severus and Maximinus Thrax.
Stylistically, Regalianus' coins imitate the coins of the Licinian emperors, though they are of lower quality, often in a very rough style and with spelling errors.
How Regalianus was defeated and died is unclear, given that different sources give different answers.
The generally accepted theory concerning Regalianus' demise, forwarded by the Hungarian archaeologist Jeno Fitz in 1966, is that Regalianus was killed in a raid by the Roxolani, perhaps working together with some of his own men, after bravely having fought the rebelling tribe for some time.
