This is an English translation of a book originally published in German. It contains most of the standard coins issued from 1800 through the publishing year. So naturally there are no Euros. There is also (intentionally) no record of notgeld. However the pictures are crisper than those in the "Standard Catalog of World Coins". There are a few different pictured coins that show this is not just an extract from other catalogs. You will find no KM numbers as references.
One big advantage if this book is the Synopsys of history of various German States and the images on their coins.
Example:
Bavaria takes its name form the Baiowarii tribe that inhabited the area about A.D. 500. The territory became part of The Frankish Kingdom, then the Carloigian Empire, Passing in 1180 to Otto III of Wittelsbach, an ancestor of the modern rulers of Bavaria.
