A Catalogue of the Muhammadan Coins in the British Museum - Arab Byzantine and Post-Reform Umaiyad - Walker John

A classic, but still a highly important reference book in Arab Byzantine and Umayyad coinage. The book is a modern reprint, and is highly sought after by collectors and dealers who so scarcely come across it, especially when looking at coin descriptions that cite this work. This reprint also includes scans of the plates (coin photos).
