This book covers coins of the Eastern Roman Empire from Anastasius I (491-518) to Constantine XI (1448-1453) with an overview of the period of Diocletian in 284 to the succession of Anastasius I as an introduction to the coinage. It is not intended to be a scholarly book but rather a quick reference for coin identification. It does not cover the holdover aureusfrom the Western Empire, coins from the collateral areas of the Arab-Byzantine, or the coins of the Turks and other successors who produced coins of similar design. It also does not cover forgeries.
