In the Philatelic Foundation grading booklet in reference to exceptional quality or "XQ" they note; "The final grade of a stamp is determined by assigning an initial grade based on centering and margins and then, if needed, adjusting that grade to reflect the various additional factors just described. Important factors such as jumbo margins or other exceptional characteristics are not included in the numerical grade but designated separately with a "J" or "XQ" designation." .
