I told her that those boys were wrong and that there gold plated/metalic cards were just as fake as hers.

Then she told me that the boys whom made fun of her, all hadd 'real' gold plated/metalic pokémon cards. And I told her that pokémon don’t sell metalic cards like that. And today she ask me if those metalic cards were fake too. Apparently she took one of the metalic cards to school, and some boys in her class started mocking for bringing and showing off a fake card. Fast forward to this week, summer vecation is over and she is back to school. I didn't explicitly tell her those were fake tho.

She also bought two 'gold' plated/metalic cards. All of them was clearly fake unfortunately. My 9 year old half sister bought some cards while on vecation in Spain this summer.
