Hello,
on the wiki page “Republic of the Congo (Léopoldville)” it's mentionned :
- Republic of the Congo (1960–1964) which didn't issue any coin,
- Democratic Republic of the Congo (1964–1971) which writed “Democratic republic” on coins.
So the name of this “period sub issuer” is problematic, without mentioning the fact that Leopoldville was renamed to Kinshasa on 1966
So in the Numista catalog we might forget the “Republic of the Congo” and name the issuer from 1964 to 1971 :
Democratic Republic of the Congo - first issue
Then since 1998 the issuer name might be :
Democratic Republic of the Congo - second issue or “reborn” to be trendy :)
