The fourth volume in the series of Studies in the Aman ur Rahman Collection (SARC) covers the coinage of the Iranian Huns and their Successors. At about 2.450 pieces this is probably the most complete assemblage of coins from this period, and also includes a substantial number of hitherto unpublished coin-types. Still the collection is further augmented by reference material from all major museums of the world, so that almost every known type is covered. The aim of this volume, by providing a commented and most complete view of the entire coinage of the Iranian Huns, is to make coins as a primary historic source accessible to the reader and usable for further research for all historic disciplines. The groundbreaking book by Robert Göbl from 1967 is hereby considerably enhanced and partly revised. The book contains 10 chapters, the Kidarites, Dinars (of the Kidarite and Alkhan period), Alkhan, Tobazini, the Hephthalites, Sasanian Coinage and Imitations, Nezak Shahs, Alkhan-Nezak Crossover, the Western Turk Period and finally Gandharan Copper. This term is newly introduced and covers a phenomenon which has been labeled “Kashmir Smast” before. Each chapter discusses the numismatic evidence based on thorough typological analysis and a short historical overview summarizes the written sources. The catalogue is arranged by coin-type but pictures every specimen in the Aman ur Rahman collection. In addition, a fully illustrated typological index is provided.
