Nice!
No one knows if the result is by design or an accidental, limited edition, collectible, never to be repeated, molds destroyed, design. Put a number on the label (1 of 12!, 2 of 12!). Who knows, you could have the next collectible craze not unlike Beanie Babies. Accept subscriptions in advance, in limited numbers, naturally, to maintain demand. Before long you'll find your bars on the secondary market selling for hundreds of dollars as bidders fight to get one of the few bars issued in October, 2013. Some will convince themselves that the October 2013 issue was good but "I really wanted the November 2014 issue. It was fantastic and is much harder to find."
You have a gold mine on your hands.
