"One account describes how a single shipment of 7,771 bars left the city in 1549, four years after the lode's discovery. Each bar was about 99 percent silver and weighed more than eighty pounds...

They were watched by more than a thousand Indian guards who in turn were watched by squads of Spanish pistoleros."
