Wikipedia disagrees with you: https://en.wikipedia.org/wiki/Sheld...rading_scale
And so does William Sheldon. The author clearly states in the book that he came up with the 1-70 quantitative scale for condition (not value). He then posits that value would be easily derived from the numerical (grading) condition using the scale (which turned out to not be as simple as he believed).
Sheldon thus introduced:
1. The 1-70 condition or grading scale, and
2. A system for pricing based on the quantitative scale.
The scale was enormously successful and the de facto standard in use today with minor modifications and enhancements. The pricing system - not so much.

THE MAN IN THE ARENA, Theodore Roosevelt at the Sorbonne Paris on April 23, 1910: "It is not the critic who counts; not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat."
