Diadumenian Billon Tetradrachm of Antioch, 217-218 AD. 26,00mm, 13.27g.

Rev: dot DHMARC dot EX UPATO, dot D dot E dot (across 
fields), eagle standing left on sacrificial victim, wings
spread, head and tail right, holding wreath in beak.

Notes: At the time of striking the coin, Diadumenian
was only nine years old and his presentation wearing
a cuirass was very optimistic. The portrait, very 
different from the image used by engravers in Rome, was
most likely engraved in Antioch itself, and is very 
realistic which leads one to believe that the engraver
had actually seen the young boy. 

This coin: Ex Munz Zentrum, early 1980s. , Prieur
248.26.
