My niece Allana (8) that died in 2002 had a nice big folder full of Pokemon cards her & my son collected & shared together when Pokemon first came out around 2000's. I bet they are worth a lot. I doubt my sister would sell them. They loved them cards.
No matter how much money I got I’ll never pay for this crap and I was a big Pokémon nerd back in the day. I saw the movie in theaters, had action figures, ran home from elementary school to watch the show in time, cards, games, etc. Nostalgia isn’t worth all this over priced crap. I’d buy the ones that cost cents and I’d be just as happy. Everything is overhyped and overpriced nowadays.
