Sasanian Empire coin identification help

This coin is the subject of this post.

I found a few candidates here using this search:

But they are all so similar that I cannot seem to figure out which one this is.

I am also very new to this hobby and an not sure my eye is trained enough to spot the telling differences.

Thank you much! :)

Welcome to Numista!

Here are some helpful references for identifying Sasanian coins:

Your coin appears to be either from Khusro II or Hormazd IV,  but I can't tell the mint or date. Hopefully another of our members more knowledgeable on Sasanian coins will be able to nail down the ID more specifically. 
 

Seeker55, thank you for this information. I can see that it is going to be a tough job trying to identify it.
