the grade should be the grade, and anything else should be separate.
Eye appeals part of the grade though so you have to take into account what the damage does to the overall look. For example a scratch away from the focal points will have less of an effect on a details grade than a harsh cleaning or bad environmental damage. They may have the same level of detail but the scratch may be a f details scratched while the other is a vg with how the eye appeal was destroyed.
You could go off just the detail but youd be applying a different standard to those coins than the others.

is it possible that lower tier TPGs (that's code for lower than PCGS and NGC,) tend to grade a little more favorably?
Thats generally the case for top grades which is one of the reasons they arent at the top of the food chain. Its absolutely the case when talking about basement slabbers. Try and find an SGS modern thats not a 70, thats a true rarity.
