Finishing 3rd on the Halloween Event 2018 leaderboard is the only way this unique knife ever entered the game, so no new copies can appear. For a collector hunting event trophies, that combination makes it a piece you wait on rather than shop for.
Questions players ask
How much is Bronze Hallow worth?
There is no stable price: trophies rarely change hands and deals happen privately. The number on value lists is symbolic.
Can you still get Bronze Hallow?
No. It was awarded for a leaderboard place in an event and is not given out again.
