There’s an unusual “Coinage of Griquatown” which has flooded South Africa (pictured). Is it a national coinage? I could dispel the mystery by Googling it -- but I'll keep the mystery alive. Anyway, I don’t yet know the answer, nor does anybody else I know. OBSERVATION: It surely is genuine South African coinage. At the same time, this might suggest that anyone could mint anything and nobody would know the difference: “Coinage of Cape Town”, say, or “Coinage of Koperfontein”.
