Ha, yes, value is a tricky thing to assess...especially your own! Another way to look at it is to think about how much you'd have to charge, such that both you and your client would have to bring your best energy to the session.

If you charged $100/hr, you'd have to run 3–4 sessions per day to make $100,000/year, so you'd only be able to bring at most 1/10th the energy you could bring to a $1,000/hr session. In a sense, charging more creates value by signaling to your and your clients brains that: "This is requires all available focus, because we're about to make MAGIC." (:
