As these cards were pack-pulled and immediately placed in sleeves back in the 90s, they are in NM to Mint condition with sharp corners, edges and coloring but may have factory-produced refractor lines/print lines, which are common with most refractors, including sport-related ones. 

Two sport card shop owners who reviewed the set of 90 refractors that included this card claims that refractor/print lines do not effect the overall grade of a card but may effect surface grading of a card. They also note that, in their experience, PSA is "kinder" with refractor/print lines in their approach to grading since these lines are the result of the printing process and not consumer-related damage.
