The hat that stole the spotlight at the GRAMMYs last month is up for auction.

Pharrell Williams placed his Vivienne Westwood "Mountain" hat on eBay late Thursday night, with a starting bid of $200—the price he says he paid for it.

All proceeds will go to his charity From One Hand to Another, which seeks to "change the world one kid at a time by giving them the tools and resources to meet their unique potential and empower them to nurture curiosity by learning through new technologies, arts, media and motivation."

Perhaps not to coincidentally, bidding is open from now until March 2, the same Williams performs "Happy" at the Oscars, and just one day before his album, G I R L, releases.

Despite its respectable starting price, at press time, bidding had climbed to more than $10,000 within only minutes of availability.
