Currency

Dakar uses the FCFA (usually abbreviated even further to CFA and pronounced "see-fa".

French-bank based Francs.

Current exchange rate is around 500 CFA = 1 US Dollar.

Interesting enough it took me a week to find out what the design was on the coin.

It's a fish. Somebody told me that there is a "Ray" just off the coast that looks like that, but another told me that the design is a representation of how they filet and bone mackerel here on the shore. I cannot confirm nor deny either of these claims. It is obvious though that it IS some kind of reference to their fishing industry. What's really gonna get you is when you look at the city from above and realize that the roads were built to make the design as well.

I'll see if I can come up with a picture to illustrate this.
