This is from a PM I sent last week in response to finding missing editions and their value:

The seven editions all vary in price with the first three being by far the most expensive. However, the third edition seems to be the most rare of the first three.

Estimated Value (based on the collectors I deal with) depending upon condition of the book:

1st $100-$300
2nd $100-$200
3rd $100-$500
4th $50-$85
5th $60-$90
6th $35
7th $35

The value increases, especially in the first edition, if signed by Mr. Kelley.
