Community price on backpack.tf: 21.0 keys, last changed 2025-11-17 (11mo ago). The live quote above, 13.4 keys, is 36% lower and last moved 19d ago. They are different measures: the quote is what traders and bots are asking and bidding on the classifieds right now, and it moves for thousands of items every day; the community price is a suggestion accepted by vote, which changes only when someone argues it should. A quote well away from the vote is usually a price that is about to be re-argued. Community prices from backpack.tf, read under an hour ago.
Steam Market asking price: $89.37 — the lowest of one listing for the Bubbling effect when we looked on 2026-10-08 01:23 UTC (5d ago). This is what a seller is asking, not what anything sold for. Steam pays out in Steam wallet funds, not cash, and Valve takes roughly 15% at the till — so asking prices there run well above the 13 keys, 28.55 ref shown above, which comes from the keys-and-metal market on backpack.tf. The two are different markets and are never blended. Steam lists the item as “Unusual Sergeant's Drill Hat”, with no effect in the name — the effect comes from the individual listing.
