Yes, I am actually quoting myself. I promise there's a valid reason, however.
Its about an idea that came out of Kay's Money Machine thread, about "dustmoney" - jink associated with the Dustmen. I was thinking, given the enormous ammount of varied coinage that passes through the Cage, many Sigilites might have a preference as to exactly what coin they put in their pouch or pocket. Not necessarily a life-or-death issue for their beliefs, but a matter of preference. Just like a berk might prefer to shop at a store run by a fellow factionmember, he/she might find a certain kind of money more philosophically comfortable.
Its easy to imagine Upper Planar types only accepting coins that have come from morally acceeptable planes and regimes, properly shiny and blessed. Hardcore Athar on the other hand, might refuse to accept any jink that's been minted under the auspice of a deity. It strikes me as a nice addition to the character of Sigil, and also provides more rationele for the existence of moneychangers in the Cage.
So the topic for discussion is: What other groups might have coinage preferences and what might they be? How can we make this neat idea a part of Sigil?
Thinking about the factions:
The Sinkers would probably like old and rusty coins of various metals, while the Sensates would probably be more inclined to accept money from exotic prime worlds or metals.
