Aureus - Hadrian P M TR P COS II FEL AVG, Felicitas

Struck in 117 AD, the year Hadrian came to power under the most contentious circumstances of any Antonine succession. Trajan died in Cilicia before officially naming an heir; the adoption was announced posthumously by Trajan's wife Plotina, a claim widely doubted in Rome and resented among the senior military. Hadrian moved quickly to consolidate legitimacy through coin issues invoking Felicitas — the personification of prosperity and divine favor — a pointed message to a skeptical Senate that had already seen four of its leading members executed in the accession's opening weeks.

The COS II dating places this firmly in the transitional months before Hadrian reached Rome in person.
