South Sudan 🇸🇸 series [Risolto]

Would the 2011-2015 notes be considered different series for South Sudan? Due to some notes changing but some staying the same, for example the 5,  50 or 100 staying the same except adding a date but the 25 became a 20 or the 10 went from blue to green

Considering the design is the same (even though some colour scheme and denomination changed) I'd argue it's the same series.

Thank you for your help! Mostly needed to know for organizing my collection

In my opinion, only one series has been issued since 2011. Minor changes, like year date added or some minor colour changes are not considered as new series. Like the Australia polymer series, the first series of polymer notes (excluding the $10 1988 commemorative) were issued from 1992 to 2015. The current series (Next Gen series) started in 2016.

Thank you, this is helpful info for organizing my collections, all notes not just South Sudanese
