Does Togo export coffee beans? From my limited knowledge of the area, it doesn't seem like it has the right conditions to grow it.
If it does export a fairly significant amount, then the domain might be worth something (especially if it's high-grade coffee), but given the small size of the country (I'd assume 5 to 15 million inhabitants) and the relatively low income of the country, it's probably not worth very much.
If you had a larger country and/or a country that exports a lot of coffee (i.e. Colombia), you might have a better domain.
With the above assumptions, I wouldn't appraise much higher than reg fee
