5 Francs Burundi 1980 - Mint

Hi all.
I was investigating about the 5 Fancs Burundi 1980 KM#20. I was wondering where the coins was issue.
I couldnt determinated which is the Mint of the coins.
The closest I got was this site : http://colnect.com/en/coins/coin/3513-5_Francs-1960~Today_-_Circulation-Burundi

But, is a different coin with different KM#, but it was to have an approximate idea.

Thank you very much.

Belgium mint before the second republic of Jean-Baptiste Bagaza (1976-1987) then Pobjoy mint
But during the second republic, the mint of coins of 1976 and 1980 is unknown
However, if one can draw a parallel with neighboring Rwanda (same post-colonial situation, same type of coin), the British Royal Mint might be the manufacturer.

Is it this one?

Hi friend. Yes it is the coin. But any of the site that you posted inform about mint of the coin. It means where the coin was strucked.

I am searching the place where the coin was issue.

Thank you very much.
