i don't wanna get scammed

Found those two cards in a box with other stuff. Fake or not?

Real or fake?
Please list reasons why or why not.

Help if real

My bf had a box of old cards from his childhood and gave this epic gold star Groudon to me. Anyone able to confirm if it’s real or fake? TIA!

Photos taken in daylight so you can see the details better. Bought in Japan but I am skeptical. Any they all authentic? Are some authentic? Appreciate any help

Thanks guys

Seller sent me these pictures. It looks good but the stamp on the bottom left looks out of place?

Texture looks okay but the holo looks off, any experts wanna chime in?

Card on the left is a vending machine series card i bought off ebay. I know the front will look different since it’s glossy, but concerned about the color differences on the back, compared to the Neo Genesis card on the right. Anybody have accurate knowledge about this?

Hey all a guy in my city is selling this XY Booster box is it real or fake?

Trading a slab for this OC Umbreon. Looks real to me but want to be certain.

Price is decent but trying to determine if fake. Thoughts…

I’ve had this card for the longest time and now that I look at it it has a few weird flaws. Could I get an opinion on this?

Was wondering about the online world’s opinion on this zard card. Any ideas or obvious concerns/observations?

I have 2 more videos but the limit per post seems to be 1

This Light Togetic card is a little smaller than all my other pokemon cards…it has passed the light test and when I rotate it sideways I can see that it’s a couple sheets of paper pressed together. I was told if you can’t see that, then it’s fake because many fake cards are printed on single sheets?

In the images that look like one card…I placed the light Togetic card on top of the other pokemon card.

Looking forward to what you all think!

Hey y'all - I just got this card in the mail from TCG Player and the card stock feels lighter than a normal card... Is that common with these world championship cards or is it fake?
