We are a professional company with over a decade of experience in the financial commodities markets.

We are a branch of the Czech Numismatic Society. Unlike most other local branches, the Prague Grosz branch is a virtual branch. It brings together amateur and professional people interested in Prague grosz and their works from all over the Czech Republic and abroad. We operate a database of medieval coinage.

Bringing together those interested in numismatics and related fields. All about coins, medals, paper money, orders and decorations. A library is available for members of the association.
