The comma may be official in South Africa, but it's not a usage most English-speakers are familiar with, nor what NIIC uses. Similarly, the interpunct was officially advocated in the UK, but its use would most likely cause confusion nowadays. It'd make more sense if Euros or possibly the South African Rand were being used. (The latter has bigger problems.)
