This set consists of 660 standard-size cards. Cards were primarily issued in 15-card wax packs, rack packs and hobby and retail factory sets. Card fronts feature a distinctive gray border background with white and yellow trim. Cards are again organized alphabetically within teams and teams ordered by previous season record. The last 33 cards in the set consist of Specials (628-639), Rookie Pairs (640-653), and checklists (654-660). Approximately half of the California Angels players have white rather than yellow halos. Certain Oakland A's player cards have red instead of green lines for front photo borders. Checklist cards are available either with or without positions listed for each player. Rookie Cards in this set include Craig Biggio, Ken Griffey Jr., Randy Johnson, Gary Sheffield, and John Smoltz. An interesting variation was discovered in late 1999 by Beckett Grading Services on the Randy Johnson RC (card number 381). It seems the most common version features a crudely-blacked out image of an outfield billboard. A scarcer version clearly reveals the words "Marlboro" on the billboard. One of the hobby's most notorious errors and variations hails from this product. Card number 616, Billy Ripken, was originally published with a four-letter word imprinted on the bat. Needless to say, this caused quite a stir in 1989 and the card was quickly reprinted. Because of this, several different variations were printed with the final solution (and the most common version of this card) being a black box covering the bat knob. The first variation is still actively sought after in the hobby and the other versions are still sought after by collectors seeking a "master" set.
