6 sold on the Steam Community Market in the 24 hours to 2026-09-05 16:01 UTC (under an hour ago), listed there as “Summer 2019 Cosmetic Key”. 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.
