Had the same problem with opening 1996 Pinnacle Summit boxes......the cards were starting to stick together.....That was about 5 years ago....I would think that now....their struck like glue now! Sorry...I don't have the answer to your question. Best regards, David
I've been putting my Topps sets in binders (the few I hadn't). 2001 Topps, green glossy cards. Opened the box and half of them are are stuck. Started pulling them apart, now they are useless. Looks like I will be putting that set together now.
Hopefully you can find a remedy, but I have a feeling it's a goner.
get them into the driest (no-humidity) location you can for awhile, then go about manually detaching them. The moisture in the air mixing with the finishes on the cards is what makes them stick together. Glossy cards always will have more issues with it.
I recently came on to literally millions of cards that had been in storage for years. The heat is what I think causes the cards to stick. Of course, the glossy cards are the worst. What Jeffo65 says is what I suggest also. Once you get them halfway separated, fanning the "deck" will help loosen the cards too. Otherwise, I have found no surefire solution to this sticky problem. Good luck.
I agree with the last 2 posters. That is how I get mine to unstick. Some may see some light damage to the finish, but all in all they separate fairly well. It's a pain to do it though. I have been trying not to pack cards into boxes too tight, but even that may not stop "the stick".
