Collation: The distribution of the cards in a wax box. A wax box with good "collation" will have very few, if any doubles, and will yield the stated number of inserts. Bad collation means that you don't get an even distribution of cards in the packs. That is, if there are 12 cards per pack and 500 cards in the set, you would have to buy 42 packs for perfect collation. Anything above this is personal opinion. However, if you're getting duplicates inside the same pack, this is extremely bad collation. Upper Deck has been accused of bad collation very frequently.
