Catalogues and Books

1] Standard Catalog of World Coins

The Standard Catalog of World Coins is a series of numismatic catalogs, commonly known as the Krause catalogs. They are published by Krause Publications, a division of Active Interest Media.

The by-century volumes list by date virtually every coin type, most of which are photographed, with mintage and other information, plus market valuations in up to 5 grades. Listings are by denomination rather than series, as in earlier World coin catalogs. The proprietary Krause-Mishler (or KM) numbers are widely used; for just a few countries earlier systems such as Y (Yeoman) and C (Craig) numbers are given instead.

2] Standard Catalog of World Paper Money

The Standard Catalog of World Paper Money was a well-known catalogue of banknotes that was 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, but are also referred to as “Krause” or “SCWPM.” Since the mid-1980s the titles have been owned by Krause Publications, and from 1994–2016 were under the editorship of George S. Cuhaj, and subsequently by Tracy L. Schmidt.

The numbering system uses an integer to identify a note. The sorting of notes is usually by issue series/date, then ascending by denomination. Some varieties also have an alphabetic prefix, with a capital letter or letters.
