The most coveted shoes in all of cinematic history, and one of the famous movie props of all time, are these Ruby slippers from The Wizard of Oz. Most recently, they were auctioned in 2000 and garnered a winning bid of $666,000. Which is remarkable, as these aren’t the only pair.

There’s a pair permanently on display at the Smithsonian Museum, as well as a pair that was stolen from the Judy Garland Museum in Grand Rapids, Minn., in 2005. There are 3 other known pairs circulating around, and these could be worth as much as $2-3 Million now.
