Coin types include:
- stiver (small; possibly ten or twelve stivers in a shekel)
- shekel (moderate, 1 shekel may be higher than average wages for a day's labor; Isaac in "Perdido Street Station" offers some ghetto garuda a shekel per day as payment to be his study subjects, and they consider this a decent offer)
- guinea (large, and available in paper form; ten guineas is too much money for several doses of a rare street drug called dreamshit)
- noble (more than a shekel).
Gold is also used as money, and it is valuable. Yagharek pays Isaac in gold, and a handful of gold nuggets is apparently an astonishing amount of money.
There are other articles of trade available in New Crobuzon; for instance, the unnamed "merchandise" offered by Mayor Rudgutter to the ambassador of Hell.
