Differences in variants between Prize Pack series - HELP NEEDED

Hello all! Me Kob from TCG Collector back again asking for help.

We had a community member submit these two pictures of Fezandipiti ex (Shrouded Fable 038/064)'s Play! Pokémon Prize Pack variants. The person claims the left one is from Series 6 and the right one from Series 7.

In TCG Collector, we would consider them different variants - but this opens the floodgates in regards to researching other differences between the same cards across different series, more specifically in regards to where the stamp is positioned in the card.

This is a call for help if anyone has more information regarding these differences.

Commenting to follow. Wondering this myself with the release of Series 7.

I remember a Regidrago V that also had this happen, but I can’t find it again.

This sent me on a rabbit hole today and based on eBay listings it looks like at least Teal Mask Ogerpon ex and Terapagos ex have left and right stamp variants. I only checked these because I collect them.

Could you send pictures? I wonder from which Prize Packs each comes from…

These are some examples I found on eBay. Since Series 7 isn’t officially released yet I’m thinking the left stamp Terapagos and right stamp Ogerpon are the newer ones. The other stamp position seems to be more common on current listings.

prize series 7 bug catchers net is on the left instead of the right

Popping this up again if people have been able to get more examples than the ones in this thread

tcg player search shows me this

Can already predict so many orders messed up on tcgplayer. Sellers just pick a random one of those 2 to list their card, not realizing the difference

Ye, we had these confirmed already, it was the first case we discovered :’)
I wonder how many more are out there…

We also cannot trust the tcgplayer images. For example, Gengar VMAX tcgplayer image has the stamp on the right side while the actual card has the stamp on the left side.
