This 175-card set was released in February, 2004, in five-card packs with an SRP of $6. There were 12 packs to a box and 16 boxes to a case. This product has a dizzying amount of parallels and insert cards which included DK Materials which had two memorabilia pieces of each card and DK Combos which had not only those two memorabilia pieces but also had an authentic autograph from the player. In addition, many other insert sets were issued including a 134-card recollection autograph insert set. This product, despite the seemingly never-ending array of parallel and insert sets which made identifying cards difficult actually became one of the hobby hits of the first part of 2004. Cards numbered 1-150 feature current major leaguers while cards 151-158 are a flashback featuring some of today's players in a Then and Now format and cards numbered 159-175 is a legends subset. Cards numbered 151-175 were randomly inserted into packs. - 2006 Beckett Almanac of Baseball Cards and Collectibles, 11th Edition.
