I have a few decent ones that had been previously attributed. I once bought a bargain lot and a reference to ID them but I never could quite pick up that skill. I ended up selling the ones I couldn't attribute on ebay but kept the book.
I have Gobl, Mitchiner and Curtis/Askari/Pendleton and would really like to see a book on Sasanian that was worth the paper it is printed on. Des anyone have a suggestion? I get much more good out of the late Tom Mallon's site: http://grifterrec.rasmir.com/coins.html
