NGC and PMG Acquire the KM and Pick Catalogs of World Coins and Banknotes

The Certified Collectibles Group, whose companies include NGC® and PMG®, is proud to announce that it has acquired the KM™ and Pick™ catalogs, the leading reference systems for world coins and banknotes.

"The KM and Pick catalogs are two of the most famous and widely used reference systems in numismatics, and they have found a great home with NGC and PMG," said Max Spiegel, president of the Certified Collectibles Group. "As the global leaders in world coin and banknote grading, we look forward to investing in these databases to make them even more comprehensive, accurate, and accessible to collectors and dealers worldwide."

Catalog systems are enormously helpful to collectors and dealers because they facilitate identification, research and valuation of collectibles. The KM and Pick catalogs aim to assign a reference number to every collectible in existence and provide associated images, specifications data such as mintage and design details, and valuation information by grade.

The KM numbering system is named for Chester Krause and Clifford Mishler, who developed and maintained it with meticulous attention to detail in order to create the Standard Catalog of World Coins. The inaugural book was published in 1972 and eventually split into several volumes (each covering a century).

The Pick numbering system is named for numismatist Albert Pick, whose research led to the publication of the first edition of the Standard Catalog of World Paper Money in 1975.

NGC makes the KM catalog available for free to collectors and dealers through its World Coin Price Guide at NGCcoin.com. PMG includes the Pick numbers for world banknotes on its certification labels and utilizes this same numbering system in its PMG Population Report and PMG Registry. PMG also makes the Pick catalog available for free through its World Paper Money Price Guide at PMGnotes.com.
