A lot of the Secret Wonders cards had that holo pattern. I remember I did a box break a long time ago and just about every holo extended outside of the illustration.
I have 3 first edition base set cards that are kind of like this but only about a quarter of the card is missing ink. They look cool and I figure it’s a similar concept.
All three are PSA 10 I pulled them from packs from the same box. I have no idea what they would be considered but I doubt I could capture it with a camera. It doesn’t show up on my scans. They are noticeably missing a layer of ink and the holo shines through but 1st base cards are so dull with their holofoil. Might be hard to see unless in person.
Absolutely. Joey’s box was brand new and sealed yet naturally most holos graded 9’s, interestingly enough the 3 with the printing error were the only ones that got a 10. And don’t even get me started on the rares…the only thing saving me is that I’m grading some commons and uncommons of value (ie pikachu etc) and selling them. I still have a hoard of those packs but I’ll never open one again.
