Bidding started at $25. I figured if it went for under $100 it would be a cool addition to my collection/Halloween costume...

Yeah no, its over $250 already with a few hours left.

UPDATE: Sold for $597. FIVE HUNDRED AND NINETY SEVEN. For a prop barely seen in the movie, and never ‘used’. Only carried. We never even saw the horn inside it. That shot is from a production still. WOW.
