Haven't been into Pokemon cards since childhood but this story is very interesting. Someone on a Pokemon forum was able to read dots left by the printers as metadata and determined many of the Playtest cards were frauds that were printed in 2024. All "authenticated" by CGC. Would recommend reading through the below post:

I had previously seen that these go for big money. CGC even said they had the help of one of the original creators of Pokemon cards to authenticate these.

What a crazy hobby this is.
