I'd say they're all fakes. Incidentally is that the one with the GRAchomp in it instead of the GaRchomp? (the appearance of the cards that should be holographic and the 'normal' energy requirements are also a dead giveaway in these ones that they're fakes. If they're the other ones, the pack had at least one card from a different set and tended to have nine cards instead of the ten that were supposed to be in the Diamond and Pearl series packets, and the reverse holo cards just looked Ugly!
P.S. Frost put up a lovely post on fakes too
(nvm, I see you've already seen that one now)
