We have numerical grading because Sheldon was obsessed with quantitation. He also promoted the idea that your body proportions (quantitative) predicted your behavior. I refer to his Atlas of Men, 1954, Harper & Brothers, NY. and The Varieties of Temperament, 1942, Harper & Brothers, NY. HOWEVER, his scale was never intended as a grading scale. It was a pricing scale for 1794 large cents. It failed to have predictive value as a pricing scale, but copper collectors still use it as a shorthand; some think it easier to say 20 than VF or 40 than XF. Dealers, particularly those who dealt in Morgan dollars, saw it as a way to make more money by increasing the number of grades and giving the false impression that grading was somehow precise and quantitative. Discuss.
