So much for the side-to-side split. Csongor sensed that there was some kind of top-to-bottom stratification as well, and he was developing a theory that the people down toward the bottom were trading in larger blocs of money, while the upper levels were for small-timers. To outward appearances, none of these merchants was carrying much gold into the pit and none of the priests was carrying much out of it. Accordingly, he had guessed at first that they were only trading in paper and that the actual transfer of specie was happening in a bank or warehouse somewhere. But then he noticed small, sparkly objects trading hands, generally making their way from the small-timers at the top down toward the heavy hitters in the lower pit. Some wiki searching told him that T’Rain had several types of metal even more precious than gold, though the vast majority of characters in the world never even laid eyes on the stuff; it was used only to effect colossal transactions. One sort of coin—Red Gold—was worth a hundred gold pieces. A Blue Gold piece was worth a hundred of those, and Indigo Gold, or Indigold for short, worth a hundred of those; which meant, if Csongor’s mental calculation was accurate, that a single Indigold coin had a value, in the real world, of something like $75,000.
