Strange Specialized Killstreak Australium Black Box
1 sold on the Steam Community Market in the 24 hours to 2026-08-29 15:48 UTC (7d ago), listed there as “Strange Specialized Killstreak Australium Black Box”. That is a different market from the prices above: Steam takes roughly 15% and pays out in Steam wallet funds rather than cash, so its prices sit above what an item realises elsewhere. Volume is unavailable for unusuals — Steam’s name for one leaves out the effect, so every effect shares a single listing.

Interactive chart. Press the left and right arrow keys to move along the series, Home or End to jump to either end, Escape to clear.
The key axis converts at today's rate. Prices are recorded in metal, so a line that is flat in keys followed the key rate rather than standing still.
