I don't know if they are listed here, but the S&C tokens were the only 'genuine' indigenous coin currency until the ZAR period. (Not including the conundrum of Griquatown, which some people say circulated a little, but I don't believe it personally based on evidence.)
In around 1806, after the Dutch secession of the lands, the British made a proclamation making British currency the currency of the South African region, and instituted equivalency. Paper currency continued to circulate a little longer, but no coins. Gradually more British currency came on.
The main 'high denomonation' workhorses in SA were the 8 Reales, the Pagoda, and some Ducats. There was also an act requiring any issued currency to be backed by gold, which precluded new ones.
So the timeline is something like this:
Pre 1806 - Dutch coinage and notes
1806 - British coinage backed up by major workhorses, with Dutch paper being phased out slowly.
1860's - 1930's --- Some tokens like the Strachan & Co and a few minor ones circulated, mostly as currency for the indigenous populations as time went on.
1874 - The first Pond
1892-1898 - ZAR Issues
I'm actually unsure about the answer to that one , but my instinct would be the main coinage pre 1806 due to the nature of the paper money that circulated and the lack of voc influence/interest
For clarification - The VOC held the deeds but there were many dutch nationals there with divergent interests. (Aka farmers etc who couldn't actually stand the VOC) https://en.wikipedia.org/wiki/Dutch_Cape_Colony
