The catalogue is part of the series of volumes of the Sylloge Nummorum Graecorum project, which under the auspices of the British Academy aims to publish major collections of Greek coins. Each volume gives brief descriptions of each coin, along with its suggested date, mint attribution, technical details such as metal and weight, references, provenance and accession number. Text and plates are interleaved, so that each coin description is opposite the photographs of both sides of the coin concerned.The current volume catalogues the 2150 ancient pre-imperial Greek coins from Ionia in the collection of the Ashmolean Museum, Oxford. Owing to the generosity of donors like Dr E. S. G. ('Stanley') Robinson and J. G. Milne, the museum's collection is particularly strong in this area. This and the combined expertise of the contributors makes the volume a new standard reference work for Ionian coins, complete with comprehensive up-to-date bibliography and multiple indices.
