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. These catalogues are commonly known in the numismatic trade as the Pick catalogues, as the numbering system was originally compiled by Albert Pick. Since the mid-1980s the titles have been owned by Krause Publications, and since 1994 have been under the editorship of George S. Cuhaj.

Numbering system

The numbering system uses capital letters (e.g. 'P', 'PS', 'PM') and an integer to identify a note. If a note has signature or date variants, then a lower case letter follows (e.g. P120a). If a number needs to be added, and the section is not renumbered then the format is to use a suffix capital letter (e.g. P120A).

Number

The sorting of notes is usually by issue series/date, then ascending by denomination.

Variants

Regular variants start with the letter a, b, c, ... Error notes usually bears the letter x, while specimen notes have the letter s. Unissued remainders (mostly 19th century incomplete printings) have the letter r, while known 20th century notes issued with replacement serial numbers would also have the letter r. Color trials bear the variant letters ct. When multiple specimens are known, then the format used is s1, s2.
