Professional graders do about 95% of their grading with the naked eye. Magnification of 5x is only used on ultra-high grade coins.</p><p><br /></p><p>The only time that a microscope would ever be used by a professional grader is to detect alteration or authenticity on a suspect coin. And even then only very rarely.</p><p><br /></p><p><br /></p><p><br /></p><p>The grading companies had nothing to do with this practice. The idea of a damaged coin not being gradeable was in place long before the grading companies ever even existed.
