The volume gathers the Proceedings of the second International Symposium 'Simone Assemani' on Islamic Numismatics (Trieste, 29-31 August 2008). The papers, by Italian and international scholars, deal with various domains of the Numismatic research covering a wide chronological and geographical span. Seals, coins from archeological excavations, Arabic coins with Persian legends or with Chinese characters and contributions on Islamic coin collections are some of the themes of the fifteen papers published. Moreover these papers examine, among other topics, the coins from Islamic and Norman Sicily, the coinage of the Malmuk and post-Ottoman conquest of Egypt and the great export of silver from Europe to Islamic lands at the beginning of the XIIIth century.
