Lhotka, John F., Introduction to East Roman Coinage, The American Numismatic Association, New York City, 1960, Reprinted from the The Numismatist
A nice overview of the coinage from the Eastern Roman Empire (or Byzantine Empire as is commonly referred). This was meant to be used by the "average" collector of this type of coinage as the most widely used references at the time of publication (1960) were difficult to obtain. Softbound. 107 pages with 5 black/white plates
