Pharrell Williams is putting his famous 2014 Grammy "Mountain Hat" up for auction on eBay! 

The Vivienne Westwood creation even has its own Twitter account with more than 19K followers!

So far, the eBay auction has reached $10,500 with 64 bids. Don’t worry, there’s a couple of weeks left to get your money together, so it isn't out of your grasp yet!

The best part of this hat craziness is that all the money will benefit From One Hand to Another, a foundation aimed to help children in “at risk communities through the country.” Pharrell himself established the charity foundation. 

The “Happy” singer even poked some fun at Arby’s for claiming the hat is the same one in their logo! Check out his tweet to the fast food restaurant:
