Double the amount is still way too little for such a one-of-a-kind item. I can see the hole lowering the price a lot, but if it was whole then I think it ought to have sold for way more than 25 lunches. And if it turns out to have been good quality due to random fantasy-rules saying high level -> high level loot in addition to being one-of-a-kind, then it would have beggared any random merchant buying it.
