Polish replacement notes? [解決]

Hello people, I'm currently visiting Poland and received these 2 among the banknotes from the ATM. One is from 1994 and the other 2018.

I'm not sure if both are replacement notes, and if so is one them more rare than the other?

Hello.

These would be the bills.

N#207645 

N#209016 

In principle, no rarities this time. =)

Regards,

Vladimir.

The 1994 note seems to be a replacement note according to the comment section (serial starts with Y). Might interest some people who specialise in that area …

I would not know how to recognise replacement on the other note.

YE is a replacement note.

Current Polish notes use Y+letter as replacements. Z+letter is also used on some of the current notes which werre printed by De La Rue.

Well done on getting a YE in circulation, not an easy find. I got a YC 200 Zl last year from an ATM.
