Sold for: $488,750
In "Terminator 2: Judgment Day," Arnold Schwarzenegger plays a cyborg from the future sent back in time to contemporary Los Angeles. Audiences lapped up the 1991 movie's nonstop mayhem, and it became the highest-grossing film of that year.
Though it appears only briefly, the cyborg's metal skeleton made enough of an impression on filmgoers to fetch $488,750 at Profiles in History, a movie memorabilia auction house. This 2012 sale was more than twice the $240,000 paid for Luke Skywalker's lightsaber at the auction.
