Antoninianus overstruck on silver denarius
P. Gaius Regalianus was a native of Dacia and may have been a descendant of Decebalus, the famous king of Dacia who Trajan defeated. Regalianus was married to Sulpicia Dryantilla, daughter of Sulpicius PoIho, for whom he also struck coinage in addition to himself. Regalianus was a Roman general who served in the legions under Valerian I and Gallienus. By 260 AD, Regalianus was the Governor of Upper Pannonia. The details of this usurpation are seriously lacking, but it does appear from the evidence that Regalianus seized power in the aftermath of Valerian’s downfall. He may have been the commander of the legions stationed at Illyricum but was eventually murdered by his own soldiers after only a short reign.
Note: All the coins of Regalianus are antoniniani and are of extremely rare. His coinage is rather crude in style and is always found over-struck on the coins of earlier emperors. Regalianus did not appear to have minted new coinage perhaps due to his very short reign. As such, the silver content of his coinage is rather unimportant and varies considerably depending upon the underlying coinage used in the production. Coins struck on good silver metal are significantly rarer than those of later bullion issues. No attention seems to be made as to the quality of the metal at the time.
