Good evening Philip and Vladimir,
Philip supported me when doing the new page for the 20 Kwacha note N# 554417 . During my research referring to the Zambian banknote I found an official pdf file of the BoZ which clarified professionally and in more detail the occurence or better design change of all the Zambian banknotes (2,5,10,20,50 and 100) starting with the issueing year 2018. As a result it could be possible that you might consider introducing new pages for at least the remaining 10, 50 and 100 Kwacha notes of 2015, as you did for the 20 Kwacha already. For the 2 and 5 Kwacha notes there seem to be no major change of the security threads and colours allowing to go on with varieties as already done.
How can I get you the PDF file? I have enclosed a screenshot with the relevant adress in case no files could be sent directly.

With kind regards
Dirk
