9.8b
In the world of comic grading and collecting, 9.8 is the grade for a Near Mint / Mint condition comic book. The precise definition is "a nearly perfect collectible with negligible handling or manufacturing defects." The B in 9.8B is short for Blue, referring to the Universal Label. This label is given to collectibles that are simply the grade as marked, with no qualifiers or special considerations unlike it's cousin the 9.8SS.
