The Pac-Man shaped potato chip

Someone in the UK discovered a Pac-Man shaped potato chip in a pack of Walker’s Roast Chicken Crisps. What makes the item “special” is that it was cooked this way and not broken off. After discovering this “rare” find the owner decided to share it with the world by selling it on eBay. As the seller says, "you can own this miracle for yourself." The price has already exceeded £10 ($19). Is one Pac-Man potato chip worth the price of a couple bags of chips?
