Polska Encyklopedia Numizmatyczna is a collaborative online reference devoted to numismatics and the history of money. Created by collectors, researchers and enthusiasts, it aims to digitize, organize and continually update knowledge for readers in Poland and abroad. Its coverage extends beyond coins to banknotes, medals and related collecting fields, including notaphily, exonumia, scripophily and phaleristics.

The encyclopedia features articles on Polish, ancient and foreign coins; Polish and foreign banknotes; collectors, authors, designers, engravers and scholars; and institutions such as auction houses, museums, antiquarian bookshops and numismatic associations. Readers can also explore bibliographies, books, catalogs, albums, journals, online auctions, communities, information sites, blogs, databases and multimedia. Practical guides help newcomers begin collecting and editing, while thematic resources introduce numismatic periods and literature.

Participation is open to anyone who registers, and a team of experts oversees the project’s content and development. With more than 1,200 articles, the encyclopedia serves as a growing educational resource and community platform for people interested in money, collecting and numismatic history
