The auction which kicked off on February 20 will run till March 2 and the site notes the winning bidder will receive a letter of authenticity.

The hat inspired its own Twitter account named Pharrell's Hat after the star wore it at the awards ceremony where he stepped out with his wife, Helen Lasichanh.

From One Hand to Another was established by the musician and aims to give children the tools and resources to meet their unique potential.
