Issued in two series of 225 cards, this 450-card set features some of the first and last cards of retired superstars and other retired star players. The cards were issued in eight card packs with an SRP of $4. These packs were issued 20 packs to a box and eight boxes to a case. A very annoying feature of this set was the checklist numbers were so small that it was very difficult to tell what the number of the card was if a collector was trying to build a set. - 2006 Beckett Almanac of Baseball Cards and Collectibles, 11th Edition.
