If it is found, the finder would likely keep quiet about it, due to Uncle Sammy and state tax collectors trying to get their 'fair' share of the loot. So perhaps it has been found already, but the finder is keeping a very low profile. If I found it, I would not let the news get out, I would just quietly go about my business. I think I would just empty the chest out, put it back and take the goodies and go on my way.
