Polish Mysterious Treasures Price Check

Due to another individual inquiring of Polish cards I pulled out a set that I received in a trade awhile back (they were not interested in the set). At the time I didn’t realize the the Polish cards had only been released for two sets so I didn’t think they were that hard to come by.

The set appears to be pack fresh and only missing lucario 122 and the secret rare 124. I cannot find very much info on pricing so I thought I’d ask here. Anyone know a ballpark on what these might be worth or how much interest there is for them? Would listing them at auction be the only way to tell? Thanks for any help.
