August 8 or 9 in AD 117. On his death bed, he named Hadrian as his successor - at least that is what the letter signed by Plotina said. Hadrian was 41-years-old and decisively took control, and had he not, there might have been another period like AD 69, with 4 emperors competing for the throne, Galba, Otho, Vitellius, and Vespasian. I have a few coins of Hadrian. I wasn't looking for more, when this historically interesting coin turned up. This is a very early issue of Hadrian securing his transition as successor to Trajan. This coin lacks the word added later, "ADOPTIO", in exergue. However, on this coin the words "DIVI TRAIAN AVG F" declares Hadrian as "son of deified Trajan". Also worth noting that this coin inappropriately carries over the titles of Trajan for Hadrian (e.g. OPT GER DAC PARTH) - titles later not included on coins of Hadrian. Hadrian, AD 117-138, AR denarius (18.9mm, 3.32g, 7h), Rome mint, struck AD 117 Obv: IMP CAES TRAIAN HADRIAN OPT AVG GER DAC, laureate, draped, and cuirassed bust right Rev: PARTHIC DIVI TRAIAN AVG F P M TR P COS P P Trajan presenting globe to Hadrian, each holding scroll Ref: RIC II 2c p.338 You can find a nice write-up of this transition here. And an article on the aureus which might provide additional evidence that Trajan intended Hadrian as his successor. Share your coins of Hadrian, coins from transitions in power, or anything else you find interesting or entertaining.
