3 sold on the Steam Community Market in the 24 hours to 2026-10-09 03:51 UTC (4d ago), listed there as “Summer 2021 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.
