I've tried to look everywhere and even asked in-game without any help. If you're a Qeynos citizen, where are you supposed to hand in City Tokens for status (besides using them for festivals)?
(Fan Faire request!) City Tokens are now also worth status. Guildhall Commodities Exporters and Sanya the General Goods merchant at City Festivals will now pay 250 status points for them, if you don’t wish to use them to purchase festival goods.
So looks like if you don't have a guild hall with a Commodity Exporter you have to wait until the next City Festival.
