The Codex Leicester, Leonardo da Vinci — $30.8 million
The most famous of da Vinci’s scientific journals, the 72-page notebook is filled with the great thinker’s handwritten musings and theories on everything from fossils to the movement of water to what makes the moon glow. The manuscript was first purchased in 1717 by Thomas Coke, who later became the Earl of Leicester, and then, in 1980, bought from the Leicester estate by art collector Armand Hammer (whose name the manuscript bore for the fourteen years he owned it). In 1994, Bill Gates nabbed the journal at auction for $30,800,000, making it the most expensive book ever purchased.
The 1933 Saint-Gaudens Gold Double Eagle - $6.6 million
Ok, so this coin has a weird story. From what I remember hearing, the coins were made and released in a pretty large quantity. However, taking in the economic state of the country at the time, Roosevelt canceled the circulation and had the ones that got out taken back to be melted down. All but two coins were supposedly melted down. However, a small few were smuggled out somehow. Although few remained uncovered, they were later found and sent to the mint to be authenticated (the finder clearly didn't know they were smuggled out in the first place). Being illegal to own, the mint kept them. Leaving 1 available coin. It was put up in auction recently getting a crazy bid for its scarcity.

Ok, so this Indian diamond apparently use to be the largest in the world. It has an unbelievable history of ownership involving a legendary history period. It apparently has only ever been acquired through conquest and dates back to 1200s. Apart of it, in oval shape, has been crafted into the British queen's crown and is actually valued to be around $17 billion dollars, I believe.
