Ok thanks it is nice to know that I'm not going crazy. Nothing on Zeno looks close (at least to my eyes, but I agree that Zeimal 98 and 99 are close enough that I'm feeling better about this being Nakhshab). In fact, with the prominent bridle, #98 looks closest.
@finn, I'm also glad to see that your coin is a bit scyphate too.
Thanks guys for your help!
Added: @ks, looks like we were typing at the same time. Yes, I wrote to him a while back when I got my first Nakhshab and he was amazingly helpful and gracious.
