Can you help me with identification of these Azerbaijani banknotes (or coupons)? [solved]

Bought last week in the Baku old city, plenty of them sold there but no idea if fakes, coupons or temporary notes, cant find any information on internet

Will appreciate comments

These are checks of "Vahid" Charitable society. Baku. 1994.

Do you know what for they were issued? Are they mentioned on any numismatic website? I cannot find anything about them on internet.

Specifically, these pieces of paper were something like share certificates of the "Vahid" charitable society, which in reality was a Ponzi scheme company.

They are mentioned on Russian notaphilic site foxnotes.ru http://fox-notes.ru/z_rus_chastnik/BAKU-D09102020.htm

There is a link to an article in the magazine "St. Petersburg Collector". Here are scans I found for you, but they are in Russian.

Thanks for these links, I have sent my requests to add both to numista catalogue
