Referring to pg. 24
To clarify just how rich they are, according to Lelei's calculations:
1 scale = 13-17 denari
1 denari = ~5 days of costs covered
The group harvested 200 scales.
(200*13*5)/365 = ~35 years of costs covered. (200*17*5)/365 = ~46.5 years of costs covered. Ergo, if a single person cashed in what they'd harvested, they'd be set for about 35-46 years, assuming they weren't forced to sell below the lowest average market price. And that's not even counting the number of scales they haven't yet harvested (as Cato points out).
