To date, there exists a single monopolist that dictates its rules [in numismatic catalogs] – that’s “Krause Publishing House”.
Over the past 45-50 years of printing (of the hard copy edition) of this catalog, the publisher managed to ensure that the vast majority of the collectors follow the principles of its construction.
At the same time, the catalog (along with others, built on the principles adopted in the late 1950s) is very good information source, not only for novice collectors but also for many experienced ones.
The “E” is not meant to oppose or antagonize SCWPM, and any others existing today. It is intended to be the beginning of a unifying system. With its help it will be possible to unify in a single informational level all existing systems and catalogs built on these systems.
Practically all cataloging systems share a single common disadvantage. Each of them is “built” to accommodate one (or a group of) countries. If, for instance, we examine Friedberg’s system (In my opinion – the best of all existing systems today), we will see that it successfully applies in USA, but not a single other country can adapt this system, because in each of these countries there is another Friedberg who has locally developed “the best” system for their country. From a professionalism standpoint, these systems are surpassing the SCWPM, but still they have some disadvantages.
The “ES” is based only on one rule:
This means, that collectors’ issues origin is not dictated by political boundaries of “Sections” [in lieu of term “country”] or by geographical location, but ONLY by the name of the “Issuing Authority” written on it.
Shown above two banknotes “$1 1862” are belong to two different Sections: USA [on a left] and CSA [on a right], depending on what is printed on it (whose government issued it). In all modern catalogs the “CSA” is a section of the “USA” division.
From a catalog standpoint, these are two different Sections.
On a picture below you can seebanknote “5 Rubles 1934,” issued by the “State Treasury of the U.S.S.R.” as is indicated by the highlight of the red circle. But the label indicates that this issue of “Russia,” which is also a mistake, because Russia (Russian Federation) and the Soviet Union (USSR) are different sections of the catalog.
By the way, this label got another mistake. It stated that in a slab located “5 Gold Rubles”, while on the banknote printed that this is “5 Rubles”.
