Finishing 2nd on the Christmas Event 2022 tokens-collected leaderboard is the only way Silver Icepiercer ever reached a player's inventory, and that window closed long ago. As a Unique gun that only a few players own, it never trades on any open market and its price is set in private deals. There is no value history to reference here.
Questions players ask
How much is Silver Icepiercer 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 Icepiercer?
No. It was awarded for a leaderboard place in an event and is not given out again.
