I have two banknotes from the "Polish Cities" series from 1990 (uncirculated designs by Andrzej Heidrich), prepared for redenomination but not introduced for technological reasons.
I have banknotes:
The information that I found and which also suggests AI that the issue volume of banknotes is 20,000
Maybe someone has other denominations from this series to swap? Or other missing me Polish banknotes, coins or euro coins.
