it is worth a lot and $100 can set someone up in small business.
about exchange rate, check http://www.ghanaweb.com/GhanaHomePage/ec… since it changes daily.
A lot. 80% of Ghanaians earn less than US$2 a day so $1 is a half-days wages.
But if your asking what is the current exchange rate between the American Dollar and the Ghana Cedis...than that is $1.00US = $1.41800GHS.
worth much more than to you,me and others of North America.
