Sasanian Empire Drachm ID

Hello, i have this Sasanian Empire coin. 

The packaging said it was from 591-628 from a guy called Chusro II but he seems to have a beard on all the coins which mine doesn't.

The coin is between 32-33mm 

Thanks a lot :)

Hmm wow, the moment i post i find something that sort of matches:
N#43896

I guess i'm looking more for confirmation now. Is there any way to determine the variant/mint? cause i'm not entirely sure where those letters would be found on the coin, and if it's written in arabic then i cannot read it.

Yes Khusru II coin.

On reverse, the mint monogram is engraved on the right side, while the regnal year (date of issue) is written out on the left side in Pahlavi script.  

The date is not very clear to me. Most likely it is RY#3. The mint is WYH (Veh-Kavad)
