Quite difficult to make out the date and mint...
A more in focus photo would help maybe?
From what I can make out....You have the coin in hand so possibly use this as a guideline and check it out....
Date..The portrait style is from his early reign and I'm pretty sure the first letter of the date is 't'.
This gives you 4 options...Reg year2, 3, 8 OR 9.
If I had to hazard a guess maybe year 3 would be my call?

The mint could well be AS..Uncertain mint in Khuzistan.

But maybe others will weigh in with other ideas.........Paul
