Badge of 70 PP (Infantry Regiment) appears to be authentic, silver made, officer version with proper silver hallmarks and maker's marks. I've seen those badges listed by Polish numismatic dealers for around $1200. Still available.
Badge of 57 PP. 3rd version, made by Stefan Zygmaniak. Everythning seems correct, but you need close examination to be certain of its authenticity. If original, could be worth somewhere between $400-1000.
Here is mine, 1st version, in silver made by Jan Knedler
