A bank of great reserve

WHAT country has the highest per capita gold reserves in its Central Bank? The US with its Fort Knox reserves, perhaps? Or South Africa, with its huge indigenous resources? No, the honour goes to South Africa's neighbour, Botswana, with its central bank governor boasting of $4.7 billion dollars for a copulation of 1.5 million. The poor Central Bank of Ireland only holds a piffling $90 million.
