The Portrait of Antoninus
Pius
Like most Roman coins, this coin depicts the profile head of the emperor on the
obverse side. Roman portraiture had a long and distinguished history;
"veristic" or super-realistic portraits were popular in the Republic
as a sign of status and wealth. Powerful senators and orators would
commission sculptures of themselves complete with every wrinkle and defect as
prominent as possible, for these details gave them a distinguished air. (1)

This style effectively ended with the Emperor Augustus, who insisted on
portraying himself as perpetually youthful and ideal. As a means of propaganda,
this idealized view of the Head of State was an effective one, especially in
the far-flung reaches of the empire whose residents had never laid eyes on the
emperor. Imperial portraiture would tend towards the idealized after
Augustus; yet some emperors did lean back towards the realistic.

Why is the face on our coin so much flatter?
Thinking back to Augustus, we realize that much of the empire never got to
experience the emperor's presence in person. Antoninus Pius was
especially fond of remaining in Italy and glorifying Rome. Therefore, it
makes sense that the makers of a coin in Neapolis, in remote Syria, would have
no incentive to truly strive for realism in their depiction of the emperor.
Most probably they were copying the image from a second-hand source,
such as another coin.
