Depends on how fast you do them.
Crunching is a very intensive exercise, but only a small amount of muscle is active. They will use up between about 300 and 800 Calories an hour, or about 5-12 Calories per minute.
If you can keep them up for an hour, that's fantastic, because you must be using a lot of abdominal muscles to help with the work. Most crunches only work the Rectus Abdominis, which is the surface layer at the front of your belly. Even the twisty ones, which claim to involve Obliques (the deeper muscles at the sides), CANNOT activate these properly, because of the lying position in which they are performed.
Normally, crunches can't be used to burn a significant amount of energy, because they concentrate the effort on a small amount of muscle tissue, and wear it out very quickly.
Large muscles, such as the glutes (buttock) and vasti (thigh, often WRONGLY called 'quads') are usually activated if a large number of calories need to be used in a short time.

It's fairly insignificant in the scheme of things, but if you did 50 crunches everyday it might help tone your stomach.
