This new edition of LMCC remains the comprehensive catalogue and survey of the coinage of the London mint from AD 296, when Constantius I recaptured Britain from the usurper, Allectus, to its closure in AD 325 when his son and successor, Constantine I, began to shift his power base to the East. LMCC II continues our earlier expansion and revision of the London portions of Volumes VI and VII of The Roman Imperial Coinage by incorporating new types discovered since 2015 and expanding the census tables based on the population totals from several major new hoards. As Sam Moorhead notes in his foreword to this second edition, this catalogue is now recognized as the standard reference work on the London mint coins of this period and is used by both the British Museum and the Portable Antiquities Scheme when cataloguing these coins.
