The official currency of United Castia.
Jin are printed silk slips, replacing venad ore and venad alloy coins, Vanads, as the primary currency of daily life and the Castian Vanad as the regional standard.
One jin can be broken down into eight son, sixteen len, and thirty-two ban, though the latter are rarely used outside of the financial sector. Conversely, when used, four jin is equal to one vanad in sectors that still accept and utilze the vanad.
