The 1997 Upper Deck set was issued in two series (series one 1-240, series two 271-520). The 12-card packs retailed for $2.49 each. Many cards have dates on the front to identify when, and when possible, what significant event is pictured. The backs include a player photo, stats and a brief blurb to go with vital statistics. Subsets include Jackie Robinson Tribute (1-9), Strike Force (64-72), Defensive Gems (136-153), Global Impact (181-207), Season Highlight Checklists (214-222/316-324), Star Rookies (223-240/271-288), Capture the Flag (370-387), Griffey's Hot List (415-424) and Diamond Debuts (470-483). It's critical to note that the Griffey's Hot List subset cards (in an unannounced move by the manufacturer) were shortprinted (about 1:7 packs) in relation to other cards in the series two set. The comparatively low print run on these cards created a dramatic surge in demand amongst set collectors and the cards soared in value on the secondary market. A 30-card first series Update set (numbered 241-270) was available to collectors that mailed in 10 series one wrappers along with $3 for postage and handling. The Series One Update set is composed primarily of 1996 post-season highlights. An additional 30-card series two Trade set (numbered 521-550) was also released around the end of the season. It too was available to collectors that mailed in ten series two wrappers along with $3 for postage and handling. The Series Two Trade set is composed primarily of traded players pictured in their new uniforms and a selection of rookies and prospects highlighted by the inclusion of Jose Cruz Jr. and Hideki Irabu.
