Every year, San Diego hosts an event called Comic-Con (”SDCC”), one of the world’s largest comic book conventions. This year, thousands of fans converged on the San Diego Convention Center between July 22nd and 26th to meet creators of their favourite comic books, games, movies and television series. Attendees were shown previews for popular TV series such as Dollhouse and Lost , as well as movie trailers like Iron Man 2 and Tron Legacy.

Perhaps most intriguing to eBay sellers is the litany of products available exclusively to SDCC attendees — many of which, according to Terapeak’s research tools, have seen high eBay demand since the event ended last week.

In the past seven days, more than 2,500 items using “SDCC 2009″ as keywords (not counting tickets and passes) have sold on eBay.com, accounting for over $130,000 in total sales. Some of the most popular products include Green Lantern: Blackest Night figure sets, He-man reissues, Twilight figures, Kidrobot vinyl toys, and Star Wars collectibles. And despite the high prices (many are already selling for over $200), the sell-through rate on these listings is an impressive 76%.

As always, Comic-Con will be back next summer, so if you’re an eBay seller focused on collectibles, perhaps it’s worth making the trip to sunny San Diego! (Really, is it ever not?)
