I've noticed that cards from this set and some other 90's sets tend to get sticky, sometimes leading to the cards getting damaged. Some that I had stored in boxes have become so stuck together that they end up ruined when pried apart. I have also ordered some from this set online recently, and can tell that the seller was having the same problem, as some of the cards had a little bit of damage from being stuck to another card. With the dark border on this set, it can be pretty hit and miss ordering cards that aren't showing some damage. I also just got some 1993-94 Parkhurst cards in the mail today that look like they were suffering from the same issue: bit of white showing where two cards had to be pried apart. Some cards from this era that I've had in an album in the glossy Ultra Pro pages also felt sticky when I took them out, but were not damaged and felt like they went back to normal dryness after being exposed to the air for a while. While most of these cards have very little value, it is certainly an annoying problem to have. 

If you do a search of teh Forums for "Bricking" you will find countless threads and posts about exactly this.

I came across an older baseball set that had been "bricked". I searching for a solution I found multiple ideas on how to save the cards (at least some) ...heating with a blow dryer (doesn't really work as it doesnt warm them up enough, heat gun maybe?) Freezing them warped the cards and didnt really work, adding steam via steamed up bathroom or prying apart over a pot of boiling water (doesn't really work and your adding moisture to cardboard) simply prying apart, which generally damages the card and finally found a degree of sucess with microwaving them. (Some separated fine, some warped, some actually burned, some separated but with transfer/damage) Probably lost 30% (may be closer to 40-50 but still better than losing them all)  Apparently this is a common thing with cards from the 90s

I used to make a suggestion in those threads. But gave up; it fell on deaf ears.  ASK AN EXPERT...contact a paper conservator.
