the supes 1 was a formerly cgc'd 4.5 or 5.0 (can't remember) slightly restored copy...had some glue and slight color touch removed (though miniscule remnants of both were left).... not originally "un" restored, but "de" restored, so to speak... initial work was so minor, it made sense to remove, and thus, to many, make it more valuable, though it is the "same" book ... but perfect example of how removing the resto, lowered the grade from a 4.5/5.0 purple to a 3.0 blue...but increased the value by 50%... in this case, the book looks pretty much the same, so this example would not work on every book ("de" restoring), but this one was a perfect candidate...
