Not if use of the alternate letter was intentional, as I explain above it’s just part of day to day maintenance of a die. And also difficult to prove it’s not just partial die fill of the lower limb of the ‘E’ . But it’s a grey area in that some collectors enthuse about mis-strikes and die flaws, incidental dots and dashes and the like. To my mind a true variety is a deliberate planned change in the design on the die, the flan (weight, metal composition, polishing ) or a significant accidental change through the act of man. Obvious date width differences might just creep in in the later years when die to die differences were rarer. And not all variations even if rare attract a premium, desirability to collectors plays a major part along with whether published or acknowledged by an accepted expert in the field (Freeman, Gouby, Sessions et al).
