Cyzicus held neokoros status — the honorific title granted to cities that maintained an imperial cult temple — multiple times over, and the civic pride attached to that designation was aggressively broadcast on local bronze coinage throughout the third century. By the sole reign of Gallienus, with the empire fracturing under the Gallic breakaway state to the west and the Palmyrene sphere expanding to the east, cities like Cyzicus continued striking autonomous civic bronzes partly as a assertion of local administrative continuity amid imperial collapse.

Provincial bronze production at Cyzicus effectively ceased shortly after 268, making this among the final issues of a mint tradition stretching back centuries.
