This week three items up for auction for geek culture aficionados, all of which receive my Geek King Seal of Approval and any would have a happy home on my mantle. (Remember, Geek King and Queen wannabes, it's never too early to curry favor for next year's voting.)

First up is this Second Century Roman Glass d20. Yep, who knew they were rolling d20s back in Ancient Rome? It's on auction at Christie's Auction House for a mere $17,925.

Too rich for your blood? How about this 1923 copy of the Lindisfarne Gospels signed by JRR Tokien himself? This book apparently helped inspire his invention of the elvish script Tengwar. It's on eBay for a "buy it now" price of $4,500. Thanks to Charlotte for sending me this find.

Last, but by no means least, you could own the hat, the cunning hat, of Jayne Cobb. No mere replica or knock off this, but the very hat worn by Adam Baldwin in Firefly. It's being auctioned for charity this fall. Don't remember it? Here's the clip that introduced the 'verse to the wonders of Jayne's hat. A man walks down the street in that hat, people know he's not afraid of anything.

As always, please feel free to send me nominees for the Geek King Seal of Approval. This concludes this royal announcement.
