Whether you didn’t get to attend Nerd HQ or simply weren’t victorious at one of the many on-site auction panels (including Zachary Levi and Nathan Fillion), Nerd HQ is still offering fans a chance to own a piece of the event.

The Nerd Machine and Nerd HQ are hosting an online auction on Ebay, with “select memorabilia and one-of-a-kind-pieces” that were signed during Nerd HQ this year. All proceeds from the auctions will go toward Operation Smile, Nerd HQ’s charity of choice.

Items up for auction include an Xbox One signed by all 75 panelists of Nerd HQ (including The Walking Dead‘s Norman Reedus and Andrew Lincoln, Supernatural‘s Jensen Ackles and Jared Padalecki, Jeff Bridges, Nathan Fillion, Felicia Day, and many, many more), a Captain Awesome Statue Head from Chuck signed by Zachary Levi and Yvonne Strahovski, a pair of Converse signed by the cast of Supernatural, and Star Wars and Star Trek ornaments, signed by Wil Wheaton, Alan Tudyk, Chloe Bennet, and more.

You can find the complete auction listing, as well as instructions on how to bid, on NerdHQAuctions.com.
