Case contains 48 mint and factory sealed sets. 66 cards per set. The factory sets are extremely difficult to find. Case has been opened to verify its contents. Look for rookies of Fred Couples and Mark O’Meara. The set features all the greats of the day such as Jack Nicklaus, Tom Watson, Lee Trevino, Tom Kite, Ben Crenshaw, Hale Irwin, etc. This is a great case to break down for grading purposes.
