A hat that touched a famous head just sold for millions: The chapeau of Napoleon Bonaparte, emperor of France during the 19th century.

Robin Meade, via HLN: "A guy paid more than $2 million. ... It was sold at auction to a collector in South Korea. Experts originally thought it might sell for $500,000."

CNN said this was one for the history buffs and the hat was actually owned by Monaco's royal family before the auction.

Sounds like a lot of dough, and if we compare this sale to some other royal items that went to auction, Napoleon wasn't sold ... short. Get it?
