Old bills in Yemen are worth 10% more than new ones
> In the west, we take fungibility for granted. [...] The fact that a dollar is worth the same in Los Angeles as it is in New York, or Vancouver as it is in Halifax, is worth celebrating.<p>I've experienced the opposite here in Brazil: someone who had leftover US dollar banknotes from a trip to Disney in the 90s decided to exchange them back to the Brazilian currency. Since they were old banknotes, the bank would only exchange them at a heavy discount (I don't recall how much, but it was at least 10%); if they were new banknotes, there would be no discount. So here we have the opposite of the situation in this article: new US dollar banknotes are worth more than old USD banknotes (this is not an isolated case, a quick web search shows that often old US dollar bank notes aren't even accepted for exchange).
