"Gem" of the 88 Topps is probably the Glavine rookie and the Tiffany versions, although I'm not exactly sure how to spot them. Not much in 88 Fleer, minus the McGwire, Bonds and again the Glavine RC.
89 Fleer, however, has a couple of nice errors. Keep an eye out for Jeff Treadway (Target logo in back), Randy Johnson (Marlboro logo in back) and then any of the 5 different Billy Ripken cards.
