Depends on where you are and how much you are willing to spend. In my area clowns are found in so many collections now that the demand for them is not so high enough to make them super expensive. More expensive then a pied but even pieds are super cheap now. The fact that the female is a proven breeder (if the breeder can prove that she is) and is pastel het clown will make her more expensive then a younger plain pastel. Pastels are cheap cheap cheap but add in that she is older and experienced and a het, your looking to spend almost double for her.
