I am looking for Polish banknotes:
20 Zlotys Independence N#203499
20 Zlotys Our Lady of Częstochowa N#203494
In swap for each of them, I can offer two other banknotes to choose from:
50 Zlotys Pope John Paul II N#202649
20 Zlotys Protection of the Eastern Border N#333545
20 Zlotys Lech Kaczynski - It Is Worth Being A Pole N#309525
20 Zlotys Frédéric Chopin N#202977
