1 sold on the Steam Community Market in the 24 hours to 2026-10-07 15:59 UTC (6d ago), listed there as “Strange Professional 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.
