The Coinage of Yemen under the Caliphs 1 Michael L. Bates version of 12 August 2022 1. Before Muslim Minting Began Yemen has rich mineral resources and supported several coinages in ancient times, but there is no good evidence of any minting there for several centuries before the 1 For the coinage of Muslim Yemen in the caliphal era, there are already several good overviews of one kind or another: Bikhazi (1970); Album (1999), including Album's very brief survey of Yemen's caliphal coinage, pp. vii-viii; Lowick (1983); Darley-Doran (1987); Bates (1998); and most recently, Audrey Peli’s impressive thesis (2008) which covers the years up to 569 (1174). Peli’s thesis became available to the present author only in mid-summer 2010, when this article was in its last draft. We exchanged information in the early stages, but her thesis and this article were written independently. References to the thesis have been inserted at various points, in addition to some revisions necessitated by Peli’s new evidence. For the history, important modern works include Arendonk, Les debuts de l'imâmat zaidite au Yemen (1960); al-Mad)aj, The Yemen in Early Islam, 9-233/630-847: A Political History (1988); Sayyid, Sources de l’histoire du Yémen à l’époque musulmane (1974); and Bikhazi 1970), cited above. On Yemen’s mines, most recently there is Peli, "Les mines de la péninsule Arabique d'après les auteurs arabes (VIIe-XIIe siècles)” (2006), and Peli and Téreygeol, “al- Rad . râd . (al-Jabalî ): a Yemeni silver mine...” (2007). Jere Bacharach, Vesta Curtis, Yahya Jaffar, Stephen Nebehay, Vlastimil Novák, Audrey Peli, Peter Philps, Gerd Puin, and Luke Treadwell provided valuable help or advice with this article, for which the author is most grateful.
