I would pull the star cards and grade those. Once they come back and you compare them graded to the rest of the cards you should have a better idea of how high grade the entire collection is.
Really high grade sets can be worth a lot but who knows if you're in the position to lay out grading fees on everything. Start with the stars. If they are nice enough, contact the auction houses. This is a major undertaking but it sounds like the collection is worth it.
