Merged: Value of old Polish money

I have some very old Polish paper money and I'm wondering if someone could tell me their value or where I should go for estimates. I have a 1948 20 Dwadziescia Zlotych; and 4 from 1919 - a 5, a 10, a 20 and a 100. If you need more descriptions of them, please ask.

Thanks so much for any help.
