Ebony ~$100 per Board-Foot
Bocote ~$40/BF
Rosewood ~$25/BF
Bubinga ~$15/BF
Maple ~$5/BF
Walnut ~$4/BF
These are 4/4 (1" thick) non-bulk, small, quantity prices. Bulk prices are lower, of course.
Regardless, $100 is not a crazy price. What does bother me is that it's the same price for all types of wood.
