There are billions of dollars out there — you just have to know where to look. We’re on a quest to dig up the goods, from the most remote ends of the earth to our own backyards. And we’re charting a course to where X really does mark the spot of buri... (more)ed treasure. We’ll travel to northeastern Nevada, where more gold has been found than in the entire California Gold Rush. And in Defiance, Ohio, we’ll meet a family who discovered a bin of old baseball cards and found out that these rare collectibles are worth millions. Finally, we journey to Lodz, Poland, with treasure hunters seeking gold and jewels thought to be lost forever from World War II.
