Æ23 - Trebonianus Gallus ΝΙΚΟΜΗΔΕΩΝ ΔΙ ΝΕΩΚΟΡΩΝ

Nicomedia held the title of neokoros — temple warden of the imperial cult — four times over, a distinction it competed for aggressively against rival Bithynian cities, particularly Nicaea. The ΔΙ in the legend abbreviates δίς, confirming this was struck during the city's second neokorate grant. Trebonianus Gallus came to power under circumstances that never fully shed suspicion: he negotiated the treaty with the Goths that allowed them to withdraw after Decius's death at Abrittus in 251, a defeat in which Gallus himself may have played a destabilizing role.
