My white whale is the 1997 Upper Deck Ken Griffey Jr. Game Jersey card. Not only was Griffey my favorite player growing up, but this is from the first set of Jersey Cards ever made for a baseball set. There are only 3 cards in the set; Griffey, Tony Gwynn, and Rey Ordonez. I have the Gwynn and Ordonez cards and just need the Griffey to complete the set. The Griffey rarely comes up on eBay. There are two up right now, however. This one has a Buy It Now price of $225.00. This one has a Buy It Now price of $359.00. I don't have an extra $225 just laying around right now, so once again my white whale will have eluded me.
