There are widely used definitions for these gradesGrade, and newsletters regularly publish market price estimates. These gradesGrade allow some imperfections but still set boundaries to distinguish them from lower gradesGrade. Imperfections, while permissible, can be exceedingly difficult to quantify for acceptance criteria. Judgement and discretion are unavoidable.
