eBay buyer says card bought from my childhood collection is fake
So I’ve been selling my entire pokemon card collection from my childhood. This is the first time I had an issue like this. The customer states “Hello the good news is the card arrived the bad news is that it is very obviously a fake card. I sent a refund request and I would love if you could accept it I can send the card back if you’d like but it’s fake and I’m sure it was an honest mistake”
I have no experience with this type of thing. From some basic research into fake cards online I don’t see how it looks fake? It looks real to me. And I don’t really understand the rip test. What do y’all think, does it look real or fake? Also I was trying to compare his photos to mine and as far as I can tell it looks like the same card from my listing except for maybe a couple small white dots on the back? Idk, hard to tell for sure. How should I move forward? The card was only sold for $9 is it worth hassling with or do I just issue them the refund or what?
