Finishing 2nd on the Christmas Event 2022 gifts-given leaderboard is the only way this knife ever reached anyone's inventory, and the event is long gone, so no more can be earned. That leaderboard spot makes it a trophy rather than a regular unique knife. Only a few exist and deals happen privately between collectors. The Silver Icecrusher has no recorded value history, so there is no pattern to follow.
Questions players ask
How much is Silver Icecrusher 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 Silver Icecrusher?
No. It was awarded for a leaderboard place in an event and is not given out again.
