The inserts that usually sell for over book value are the ones that had odds greater than 1 per box (i.e. 1 per every few boxes or 1 per case), especially if the insert set had lots of cards in it. Keep in mind particular cards from a set with 5 cards in it that has odds of 1 in 5 boxes are easier to find than particular cards from a set with 30 cards in it that has odds of 1 per box. Typically the cards that are most desired are ones with the highest odds per particular card.
