In 1597 there are two changes in the position of mint manager. At the beginning of the year, it passes from the hands of Daniel Koste to the management of Hanusz Eck, before being handed over to Melchior Reysner. And it is during this third period that the above trojak is minted.
A rare variant with Reysner's monogram in the shield at the bottom of the reverse (rarer than the monogram without the border).
In addition, an interesting variant with the letter G (from Gratia) impaled on the orifice, almost invisible.
