Achaemenid attribution problems...help!

[CPK]

I've got another Achaemenid Siglos that needs to be identified but I'm finding myself stumped (again.) There just doesn't seem to be much to go on. Maybe someone here has the expertise and knowledge needed to make a reasonably sure attribution? (Hopeful!)

Here is the coin and a copy of the auction house's description:

 

"Time of Darios I to Xerxes II 485-420 BC. Siglos (silver, 5.49 g, 14 mm), Sardeis. Persian king in kneeling/running stance right, holding spear and bow, and with quiver over shoulder. Rev. Incuse punch. Very fine."

 

This would match the Carradice Type IIIb. But I don't like to blindly trust an auction house's description. What is the NumisForum consensus?

Thanks!

Hi @CPK,

Did you look at https://www.forumancientcoins.com/numiswiki/view.asp?key=siglos ?

Yes, but I must confess that my eye isn't practiced enough to easily tell the differences in styling, e.g. the drapery folds and the figure's appearance and proportions.
