Watch List notes:

Revolutionary Period, 'Abdallah al-Saffah, fals, Tawwaj 132h, obv., mint/date formula beginning in margin and concluding in field, rev., in margin: Qur'an 42:23, 1.85g (Wurtzel 42 = Miles, Excavation Coins from the Persepolis Region, ANS NNM 143 (1959), no. 504; Album M209 RRR), small part of edge chipped away, almost very fine and extremely rare. The 'Abdallah amir al-mu'minin named on this coin is the Abbasid caliph al-Saffah (132-136h). As Wurtzel notes, the coin bears Qur'an 42:23 (the verse which became the slogan of the rebels who took up arms against the Umayyads) and therefore cannot be regarded as a formal Abbasid issue. It is likely, as Wurtzel further suggests, that it was struck by a local commander supporting al-Saffah and not by the Abbasid caliph himself
