Poland currently has banknotes in 6 denominations, issued in 3 emissions (the first date is the date on the banknote, and the second is the date it was put into circulation):
1 EMISSION: (1st banknote design).
- 10 zlotys (1994/1995)
- 20 zlotys (1994/1995)
- 50 zlotys (1994/1995)
- 100 zlotys (1994/1995)
- 200 zlotys (1994/1995)
2 EMISSION: (2nd banknote design)
- 10 zlotys (2012/2014)
- 20 zlotys (2012/2014)
- 50 zlotys (2012/2014)
- 100 zlotys (2012/2014)
- 200 zlotys (2015/2016)
- 500 zlotys (2016/2017)
3 EMISSION: (same banknote design as the 2nd emission)
- 10 zlotys (2016/2017)
- 20 zlotys (2016/2017)
- 50 zlotys (2017/2018)
- 100 zlotys (2018/2019)
- 200 zlotys (2021/2022)
- 500 zlotys (2017/2017)
In the numista catalog, these 3 banknotes emissions were divided into 2 banknotes:
1 banknote (N#202134) - 1st emission
2 banknote (N#206814) - 2nd and 3rd emissions, as they have the same design, only the date differs.
However, I have noticed that in the case of a coin, if the coins are made of a different material or only covered with a layer of a different material then the Numista catalog classifies them as 2 separate coins (e.g. 50 groszy 2017-2019 and 50 groszt 2019-2024 - the first coin is made of cupper-nickel and the second is covered with an additional layer of iron).
Hence, the question, as I found a note on the National Bank of Poland's website that the banknotes put into circulation since 2017 are additionally coated with a “protective layer that increases the durability of banknotes in circulation.” That is, all banknotes of the 3rd emission and the 500 zloty banknote of the 2nd emission.
So I ask you guys, in this situation, should we also do the same as for coins? This would mean creating new categories for banknotes:
- 10 zlotys (2016/2017)
- 20 zlotys (2016/2017)
- 50 zlotys (2017/2018)
- 100 zlotys (2018/2019)
- 200 zlotys (2021/2022)
Without the 500 zlotys, because both 500 zlotys banknotes contain this special layer, so it would remain the same.
I'm asking your opinion on this matter.
