Law / Old Polish money banknotes - what's their value today? [415]

Please show me which board game this comes from then. It is illegal for a board game to print money with actual bank names displayed on it for various reasons. This note does in fact state it is from the Narodowy Bank. I think this is a note you've never seen before. It came from my pole grandpa who immigrated from Poland back in the 1900's.
