A rare and yet unpublished pattern coin was found near the city of Esztergom. The exact date and place are still in question. The importance of the pattern coin is yet highly significant in getting to know the coinage system of Hungary in the 12th century. This is a problematic age in the medieval coin manufacturing of the kingdom, due to the lack of written sources and coin legends referring to the system. Minting tools are also rarely known from the era, as they had always been treated with great attention throughout the history of coinage, and had been guarded well, in order not to make it possible to use them against the will of the legal minting authority.
