Because of their iconic stature they are now among the most treasured and valuable of film memorabilia. As was customary for important props, a number of pairs were made for the film, though no one knows exactly how many. Five pairs are known to have survived; one pair was stolen in 2005 and has never been recovered.
My dad is the director of the museum that was showcasing the pair that got stolen. The owner of the slippers told him he didn’t need to put the slippers in the safe at night, which has always led me to believe that the owner hired someone to steal them. Why? To get the million bucks that they were insured for. I mean who the FUCK would be like “ohhh yeah i have one of the original ruby slippers i didnt steal them or anything lol nope”.
