Pharrell and eBay have partnered up to auction off the now-famous Vivienne Westwood hat the super producer wore to the Grammys. The bidding is currently at $10,500.

According to Pharrell, he's "giving up" the hat to "help underserved kids gets the educational tools they need." Proceeds from the sale will benefit his educational non-profit From One Hand to Another. 

The auction began last night, with the starting bid at $200, and will be on for nine more days. Which means you have a little more than a week to get your stacks up. 

Head to Pharrell's eBay page to place your bid—and to (possibly) get a piece of history.
