Africa's outpouring of gold and that of the Soviet Union, the number two producer, flow largely to London and Zurich. At the Swiss Argor Re finery, workers process one-kilogram gold bars (right). Argor's output includes coins minted for Lesotho in southern Africa (above) and Olym pic Gold Medals. At London's Rothschild banking house, agents of five British banking concerns meet to assess daily supply and demand and to set the free market price of gold. A flip of the little Union Jack (below) signals fresh orders affecting prices.
