$1.8M is not bad, but the article also brings up a similar case in 2010 where a vase found when cleaning up a house was estimated to be worth $2M but was eventually sold for $83M?!?

Edit: it gets better. That $83M was never paid by the buyer in what may have been a protest organized by the Chinese government against the sale of looted treasures by the British. Meanwhile, the sellers were in the hook for a $14M estate tax that was based on the auction price.
