Immediately after hearing they were stopping production i seen new metazoo products at target that is a colab between metazoo and sanrio which i had to do a double take because its such a strange collab. Me and the wife got a 3 pack blister and they are pretty neat. Maybe someone already saved the ip?
Without knowing a bunch about the market i would be shocked if any of these cards were worth more than a couple of bucks. Kids like foil even more than us. Sure, have a look, but i'd err towards letting them have fun with it
