In this contribution a few remarkable Arab-Byzantine coins are discussed. They were struck in late 7th-century Bilād aš-Šām. This core province of the Umayyad Caliphate, adjacent to the Byzantine Empire, is also known as historical (Greater) Syria or the Levant. The aim of this paper is twofold: on the one hand, strengthening certain findings or assumptions of earlier research; on the other, reconsidering a somewhat overlooked hypothesis. In the first category nearly all considered issues can ultimately be traced back to questions of die cutting and die linking. As for the revisited hypothesis, it fits in the broader context of the propaganda war conducted between two rival empires at the end of the 7th century, the Umayyad Caliphate and Byzantium. This paper reflects the modest hope of a non-professional numismatist to offer the specialists some material they can build on, and to broaden, to a limited extent, the debate about early Umayyad coinage and Arab-Byzantine relations.

– Le trésor de Quseir, enfoui vers 635 AH, à la fin du règne du Sultan Ayyoubide al-Kamil, a été découvert dans le sebakh d'une maison cossue de cette cité maritime. Il comporte 593 pièces d'or et d'argent des xii e et xiii e s. et se caractérise par l'abondance de monnaies de billon égyptiennes, désignées d'après leur forme dirhams noirs ou globuleux, et pour lesquelles notre trésor apporte de nouvelles informations métrologiques Summary – The rich Quseir Hoard, discovered in the sebakh of a wealthy Islamic building, consists of 593 gold and silver coins from the 2th and 3th centuries. The hoard, dated from the last year of the reign of the Ayyubid Sultan al-Kamil, is characterized by the abundant presence of Egyptian debased silver coins, called after their shape either black or globular dirhams. The Quseir hoard provides new evidence about their wide spectrum of weight's dispersion. The hoard includes also 5 Syrian dirhams, testifying of the full integration of Quseir within the Ayyubid monetary trail.
