From Edward's scissorhands to Indy's Holy Grail, rare Hollywood memorabilia goes up for grabs

How do you put a price on a chunk of kryptonite? ”hen something comes from a beloved film, it’s instantly recognizable,” says Joe Maddalena, president of Hollywood auction house Profiles in History, which will preside over the sale of 396 pop culture artifacts from the Dreier Collection on July 28.

And recognizable means valuable. Amassed over a 15-year period by former FORTUNE 500 CEO Chad Dreier and his son Doug, the collection includes curios from iconic entertainment franchises, some of which have been appraised at up to $80,000. These days, you won’t see Marvel tossing out any Iron Man costumes with the trash (they’re kept under lock and key in the studio’s archives), but in decades past, wardrobe and props were considered junk once filming wrapped. ”When they were making movies [like Superman], they got rid of this stuff,” Maddalena says of items like a Man of Steel costume, salvaged by a subcontractor who worked on the London set of Superman: The Movie in 1978. ”It didn’t dawn on anybody to save it.”

The auction represents a chance for fans to snag a Hollywood relic — and dropping five figures on Captain Picard’s Star Trek chair or a Chewbacca head from Star Wars might also be a shrewd financial move. ”People are starting to realize that there’s no difference between buying movie memorabilia and buying art,” Maddalena says. ”But you shouldn’t buy it just as an investment. Buy it because you love it.”
