African coins of some countries

I have recently acquired a batch of African coins from different countries, finding three coins that I have not seen appear in any list of international numismatics books or online on any website.

• Congo: 1 cent, 2019
  
• Malawi: 1 tambala, 1995 (It is identical to the coin https://en.numista.com/catalogue/pieces4777.html, but with another reverse in which the FAO message "Food For All" appears)
  
• Liberia: 2 cents, 2019
  

For this reason I would like to comment on the forum to know if these coins are in circulation but have not been included in the lists because they are recent, or they are commemorative or rather they are replicas.

#2 no date = fao token http://fao-coins.info/fao-3.html
#3 a kind of commemoration (40th) of these event https://en.numista.com/catalogue/pieces83673.html

Hello, I also have those ones from Malawi and Liberia...did you manage to identify them?

No, I still haven't been able to find any of these three coins after reviewing various online guides and reference books on international numismatics.
If I can finally find a place that identifies them properly, I will point it out here with a URL or image of the book
