Monday’s Premiere Props Hollywood Auction Extravaganza XIII has some impressive items: a sword from Kill Bill, a gorilla mask from Planet of the Apes, the Riddler’s hat from Batman Forever.
These films would have been different without these pieces; some films are so connected to their props, they become symbols for the movie.
And so cinephiles clamor to get their hands on these objects that embody their favorite movies and are willing to pay a fortune to get them. $200,000 for a small metal tube, $78,000 for a suit of clothes: if it graced the silver screen, it’s worth more than gold.
TIME takes a look at the 10 most iconic movie props ever sold and you can see them HERE.
