Already in Hans
von Fritze, "Die autonome Kupferprägung von
Kyzikos: eine chronologische Studie",
Nomisma X, 1917, this
type is dated to the time of
Hadrian. In all other references I know this
type is also dated to imperial times.
But you are free to believe what you want

Is this a sign of special expertise?
