Love Pharrell Williams' famous Buffalo hat he wore at the 2014 Grammy Awards? The artist/producer is auctioning off his headline-grabbing Vivienne Westwood-designed hat on eBay for charity.

The Guardian shares that Skateboard P has partnered with eBay to sell the accessory he donned at the Grammys (and has continued to rock in other models) and proceeds will go to his educational non-profit organization, From One Hand to Another. The 100-gallon hat went on sale Feb. 20 and there are several bids already, as high as $12,000.

The auction is open until March 2 and also comes with a letter of authenticity...in case you need one. Bidders must also pre-qualify "to ensure a safe and fair auction."

"I’m giving up the Buffalo hat I wore to the Grammys to help underserved kids get the educational tools they need,” Williams said in a statement per the Guardian. “Our organization, From One Hand to Another, is committed to bringing kids experiences that ignite their passions, challenge their minds and prepare them for success.”

Props to Pharrell Williams (and his hat!) for his worthwhile charity auction. Good luck to the winner!
