Mine seems fine thus far - the gold on the front, back and spine hasn't shown any signs of wear.
They've done limited edition similar releases before - I have the BT RPG, Time of War, in the same format. So, hopefully yours is entirely a fluke.
I recommend you call their offices come Monday, and politely, respectfully let them know the strange problem you're having on the premium book, and how an exchange for a non-defective one can be arranged. Follow-up with a short, clear email (get the contact points email and name) documenting the discussion, next steps and your appreciation for their customer service.
Good luck
