What sets this issue apart from other Antiochian tetradrachms showing Apollo is that his head here shows a surprising individuality: it is clearly reminiscent of Seleukid royal portraits, most notably that of Demetrios II in his first reign (146-138 BC), which is a radical change to the design that can hardly have been a coincidence.
