As advised by vladthiengo i am opening up this thred.
As You may Know Donetsk and Lugansk as well as Crimea are parts of Ukraine occupied by Russia.
Donetsk banknotes can be obtained from different sources :

https://numimarket.pl/doniecka-republika-ludowa-2018-zestaw-7-banknotow_1561184
i have set of all 7 banknotes 50 100 200 500 1000 2000 5000 rubels
They claim to be independent but are not recognized worldwide.
https://en.wikipedia.org/wiki/Donetsk_People%27s_Republic
duo to the fact that it is an active war zone i am unable to confirm the authenticity of the banknotes other than the claims of the shops that sell it.
I can deliver more photos of the banknotes. They seem to be issued in 2018
