Review Volume III from
"This book essentially is a "type set" book of modern Swiss coins and paper currency, generally excluding commemoratives. A major component of this book is the author's creation of his own Linneaus-style (Kingdom/Phylum/Class/Order/...) taxonomic system that uses logarithmic scale calculations instead of words, coupled with date and obverse/reverse descriptions, to create literally a cataloging system of currency for a country. I wasn't expecting this, and I have never seen one created, although it's mentioned in the description. (Description was cryptic.) The author is competing against catalog systems like Krause-Mishler (KM), etc, as a comparison, but has excluded commemoratives and has limited his system to publicly circulating currency. The system may need to include edge designs for various countries as they can change; maybe this is addressed in other volumes."
