It's never easy judging such pieces. Hand made insignia was rather common in the Polish 2nd Corps, although they were generally a bit more refined than these. Despite the crude construction these evidently did take some effort, and raises the question would a faker go to this much trouble to create insignia that isn't particularly scarce and valuable? I'm afraid that I can't offer too much more than that. Perhaps there's some clues to be gleaned from where you obtained these (assuming they are yours)?
