Edit: I checked the rest of my collection and not a smidgen of mold in sight, seems like it was inside the case to begin with and grew. Would PSA be liable in this instance?
The air basically everywhere is filled with mold spores. It was probably encapsulated with the card and just slowly growing. I don’t think it’s an issue of the case letting things in.
Still very unfortunate though, especially on a card like that
When looking at the back of your card I’m wondering what would happen if you tried scraping the mold off with a cloth, but the problem with that is it would most likely wreck that part of the blue border.
AFAIK PSA does not claim the cases to be airtight or waterproof anywhere. There are several youtube videos proving the fact that cases are not airtight and/or waterproof as well.
I think you would have no recourse on this card per the wording in their Financial Guarantee.
“the Guarantee does not apply to any card that has been environmentally damaged due to improper storage or natural disasters, such as fire and flood; the Guarantee does not apply to cards exhibiting environmental deterioration subsequent to initial grading”
I don’t know that the card has necessarily been subject to a flood, but I bet they would certainly argue that at some point along it’s life it was subject to very high humidity and this is as resulted. Clearly it isn’t something you say was there a while ago so if it really is mold that is growing that sounds a lot like “environmental deterioration subsequent to initial grading”. It would still be worthwhile to reach out to them and share the photos in an e-mail and see how they instruct. Best of luck. This is surely a new one for me.
I actually just went through my entire collection and didn’t find a smidgen of mold. What’s unusual as well is the psa sleeve and cover of the zard doesn’t have any mold either…so it’s definitely from inside
