Obv: IMP C P LIC GALLIENVS AVG, radiate, draped & 
cuirassed bust right, dot below bust

handing wreath to emperor standing opposite holding spear.
Dot in wreath in upper field.

Gökyildirim hoard 2348
Cohen 1109, RIC 450 [joint reign]. This is paradoxical given the "AVG" rather
that "AVGG" inscription, but RIC explains, "The style of these coins is of the joint reign."

RIC does not mention the dot below the bust.
