1/10 Ounce Mining

The 1/10 oz Natura gold series — of which this is part — was South Africa's answer to the Krugerrand's monopoly on domestic bullion coinage, targeting collectors unwilling to hold the larger, pricier format. The "Mining" theme issued in 1999 drew directly on the Witwatersrand gold industry, which by that point was already in structural decline; South African gold output had peaked in 1970 at over 1,000 tonnes annually and had been falling ever since.

Mintages for the Natura fractionals remain low relative to the Krugerrand series, and the .9999 fineness was a deliberate commercial distinction from the Krugerrand's .9167.
