Hi all,
I’m considering doing a trade for an artset of 1st ed base blisters. I am not worried about authenticity, however on some corners of the plastic it is raised. Like it has popped off a bit. Does this reduce the value of the blister at all? Does this happen to all blisters and is just a matter if time?
Thanks in advance! 
The blister pack is twenty years old. It’s normal for the edges to lift like that. The glue does dry out.
The glue degrades over time and heat exposure --it’s not uncommon. I think it does effect the value, but I think it’s a “whatever someone will pay” kind of situation knowing the damage can worsen over time.
Yeh I’ve never got involved in blisters before so I have no idea how much the popped corners changes the value, if at all…
The problem is with the reseals. As you can imagine it would be easy to reseal and claim there’s a glue issue. This isn’t common though and I haven’t seen any questionable blisters in a long time (maybe one from Australia a couple years ago)
Just ball-parking the value, but if the pedigree of the blister is good, meaning that it’s from a known trustworthy seller then maybe 20% off based on the condition of the one in the photo. If from an unknown source like I said there’s no fixed price.
Also… it can worsen through shipping if not packed properly, since the seal is weakened. Just a heads up to have them pack it well 
Super easy to reseal these, you can get clear drying glue and not be able to tell a difference in my opinion. Thats why I sold off all of my blisters.
Thanks @jkanly and @ccrntrade. He got them in a raffle off @thecharizardauthorty around 7 years ago. However, if the corner seal popping up affects the value I may have to rethink them.
Same, but wasn’t going to mention the particulars 
Blisters are impossible to reseal !!! once you open them the paper is ripped off and its a mess. you cant open them cleanly. if you were to reseal it would look like a mess and be super obvious. This is where the premium comes from being impossible to reseal and difficult to weigh. I dont believe people are paying extra $$$$ for a nice coloured cardboard and plastic…
This isn’t true - I once had 2x resealed 1st ed base blisters recently. People have creative ways to lift the glue without disturbing the cardboard underneath. I can 1000% confirm resealed 1st ed blisters are being passed off and sold as authentic and are most definitely in the environment. The lifting seal should always be cause for concern.
Put them in the sun, or use a heat gun and let me know if you still think it is impossible
1st ed base set blisters are very hard to reseal and the ones I’ve seen resealed were blatantly obvious if you do your research. I’ve had 18 1st ed base set blisters at one time, and have seen first hand resealed ones (but very few). A lot of mine I kept are still so tightly sealed right now that using a blow dryer or putting in the sun would do nothing. Some are poorly glued and those are the ones you have to look out for as these things are 20+ years old.
A Raffle?
Sorry he clarified, he bought them off of you on eBay and was entered in a raffle and won an uncut sheet from you. Does that sound right?
I could have sold him these things years ago, but I cant even figure out how the raffles work now online. Maybe he won it is a giveaway on youtube?
Sounds a little dodgy with the story changing.
He won the fossil sheet through one of your raffles in 2014 I believe. The video is still on your YouTube and you did the raffle on an excel spreadsheet. Do you think the corners being raised is an issue anyway? I don’t collect blisters at all so I have no idea if this is a big deal to people who do collect them.
EDIT: Yeh I think it was one of your YouTube giveaways, I just misread your response.
Blister plastic comes off easy, so it could have just been the way it was stored for the past 6 years, but anytime something is no longer originally sealed it should raise suspicion. I always assume the worst whenever I buy something unless it can be proven otherwise.
Good advice, thanks:)
