About Koguja.ee

Koguja.ee is an informational catalog dedicated to collectors of world banknotes and paper money. The site was originally launched over 20 years ago and has been rebuilt as a modern catalog with detailed data on thousands of banknotes from countries around the world.

The catalog is organized by country, denomination, year, and series, and references the Pick catalog — the internationally recognized numbering system for world banknotes. Each banknote entry includes technical specifications such as dimensions, printing office, paper type, colour, and date of issue where available.

Banknote descriptions and historical context are researched from numismatic sources and supplemented with AI-assisted writing. All content is reviewed for accuracy.

In addition to catalog data, Koguja.ee publishes articles about numismatics, currency history, and collecting. The site also includes references to external marketplaces where similar collectible banknotes can be found.

We do not sell any products directly. All external links are provided for informational purposes only.
