The book provides, for the first time, a comprehensive account of the collecting and study of coins in Britain from 1500 to 1750. Many new discoveries, such as the existence of a Tudor royal collection, have been made in the course of the research. In addition, important scholars and collectors have been identified, who are otherwise virtually unknown, such as James Cole, John Harrison, Simonds D’Ewes, John Marsham and Francis Sambrooke. The development of the early university collections, at Cambridge and Oxford is also described. Many unpublished documents have been identified, transcribed and, when in Latin, translated. Most are from the British and Bodleian Libraries, but many other manuscript sources have also been used, in the UK and abroad. The book is divided into 37 chapters, which are broadly chronological, with several thematic treatments interspersed. 73 appendices cover specific topics. Finally, there is a substantial ‘Register’, a catalogue raisonée of all the people who are known to have had an interest.
