Thanks Bob, Still waiting on the Zengid book, did get the Artuqid one. I've been looking at some more coins but they tend to be in not too great a condition. Vcoins has some nice ones but expensive. I was lucky to snag this one for only a few dollars, so I can live with the condition until I'm able to afford better ones. My focus is still on Sasanian coins but I'm at the point now where I'm getting into the more pricey ones.
