Among the gems up for sale is one of Nicholson’s Joker suits from Batman, which has a starting bid of $12,955.
Fans of these films and TV shows (the auction includes items from the likes of Doctor Who and Star Trek) aren’t required to be at the Prop Store auction in order to bid.
Ghostbusters fans can get in on the action, too, with Peter Venkman’s costume from the original film (starting bid: $3,886).
According to Wired, the Prop Store in London is hosting an auction of 600 action, sci-fi and fantasy film and TV items on September 26.
