ER:Tsui

From The Heretic Knowledge Vault

As portrayed in Errant Road, the tsui is the basic unit of currency in Tsuiraku. (We have no idea whether it also has this name in the Poe-verse itself; probably not, since Meji and Ellis talk about "silvers" in a way suggesting they're the unit of currency in common use. We really don't know, but anyway, the Errant Road version is not assumed to exist in the main story.)

The tsui appears to have roughly the purchasing power of one American (or Australian, Canadian, etc.) dollar, or one Euro, in the real world -- "purchasing power" being a different thing in Tsuiraku because so many things are done magically and apparently without the exchange of money. It appears in various Errant Road threads, frequently in situations involving exchanges of a bit of baksheesh (or, if you will, bribery).
