Did my son get ripped off?

Hey guys- my son is obsessed with Pokemon, watches Pokerev all the time, and is saving up his money to buy a booster box. He really loves Pokemon.

He came home this afternoon and was really excited because his friend traded him a bunch of gold cards for some of his Japanese pokemon and other cards. But I’m almost positive the cards he received are fake. I can’t find anything about them on TCGPlayer or elsewhere.

Does anyone know the story with these? Are these types of fakes common? Are they even real TCG cards?
