As someone who worked for a card shop collating these sets, I know about these.
The boxes contained 500 cards. 4 x 500 = 2000
3 sets at 660 each = 1980
This means there were 20 extra cards in each run of boxes, or 5 per box. They were placed neatly behind the cards. to give you a bit of a visual:
extras - =
Set - ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
So the 5 cards that were tucked in the back, perpendicular to the other 495, were extras, not part of the sets.
They could be any cards.
And yes, the sequence in box 1, was the same in box 1s. then there was a sequence that ran in box 2 165 cards in. The remaining 335 cards in box 2 were in the same sequence as the first 335 (of 495) in box 1. So if Bob Dernier was the first card in Box 1, you went till you hit Bob Dernier in Box 2, to know you had the set. The same pattern held true throughout boxes 3 and 4.
Fact of the matter is, if this box is truly unsearched/untouched from the vending case, you have 75% of the set - randomly. And in great condition.
BTW, Fleer completely botched this process in 1982. This may not hold true for vending boxes/cases from 1982. We worked on several cases from that year and wound up having to collate the entire case at once, rather than set by set.
