CGC "qualified" grade
Saw this the other day and thought it was interesting. CGC is slabbing altered cards with a numerical grade, but stating what the alteration was and calling it a "qualified grade." They do the same thing in comics, and PCGS does something similar with coins, for example "cleaned - AU details." I think there is definitely a place for this in the card market. All those authentic altered Mantles out there, wouldn't it be better to grade them as say Qualified 6 - Trimmed, or Qualified 3 - Recolored?
