Problems with Krause Standard Catalog of World Paper Money

The Standard Catalog of World Paper Money is a well-known catalogue of banknotes that is published by Krause Publications in three volumes. It is the most commonly used catalog with standard Pick numbering and very comprehensive.

However there are numerous problems and inconsistencies with the catalog that have been highlighted by collectors but have not been corrected through out the editions.

The Pick Numbering System

P-1a - P (Standard issue note) - 1 (first note issued for that country) - a (variety, date, signature)

Problems in the Catalog

1. Signature blocks do not match variety. The catalog has a block of signature combination for some countries. The number listed in the variety for these signature combination either does not exist or is wrong.
2. Signature varieties are not assigned a variety letter.
3. Issue dates are not assigned a variety letter.
4. Issue date / print date combination is not assigned a variety letter.
5. The variety letter 's' is supposed to be reserved for a specimen note. But some countries have 's' assigned to a regular variety note.
6. The black/white pictures are difficult to read. Most of the scans obtained by the catalog must have been in color.
   
7. Valuations on the notes are significantly different from market value. Pre-Euro notes are over valued.
