I also do not have Gorecki. But here are some observations.
The shape of the shield of the Polkozic puts it in the B.27.1 family I think (B.27.2 has a different shape of the Polkozic shield).
It looks like B.27.1.d matches the orb/24 side of yours. The outermost circle is open around the Polkozic, and the next circle touches it: https://wcn.pl/archive/170889
The punctuation of the legend on the other side is also very close.
B.27.1.a has the orb circles not touching the Polkozic at all: https://wcn.pl/archive/172633 .
B.27.h has saltires (x) for punctuation in place of simple stops (.) https://wcn.pl/archive/328607
So, lacking Gorecki, my best guess is B.27.1.d which appears also to be the most common variety.
