William Burchell had this to say about "money" in South Africa in 1811 (source: Travels in the interior of South Africa, vol one, page 78-79):
The only money in general circulation, is small countersigned pieces of paper, bearing value from the trifling sum of one schelling. or six pence currency, upwards to five hundred rix-dollars each. The only current coin are English penny-pieces, which here pass for the value of two pence, and are called dubbeltjes. Spanish dollars are used in Cape Town, rather as bullion than as coin; their value varying according to the rate of exchange. Accounts are kept in rix dollars, schellings and stivers; although the value of estates and possessions is often rated in guilders, three of which make a rix-dollar. Six stivers are equal to one schelling, and eight schellings to one rix-dollar or four shillings currency; but the value of this currency is excessively reduced by the rate of exchange, which in 1810, was 33% in favour of England, and has since that time gradually risen to above 120%. This enormous premium for bills on England is attributable to the want of exportable colonial produce; wine being the only stable commodity, excepting a few hides, some whale-oil, and an inconsiderable quantity of ivory, ostrich feathers, gum-aloes, argol and a few other articles of little weight in the scale of general commerce.
