The reverse of this coin is quite curious since there is no sign of the expected incuse square. This may mean that the square was exceptionally large, that it somehow broke away, or that it was never there. This last possibility might go with the very unusual, but known, placement of the alpha on the reverse - at the level of the owl's neck, rather than above the head. This probably has no iconographic or chronological meaning, rather it was doubtless due to an inventive die engraver!
