Community price on backpack.tf: 50.0–52.0 keys, last changed 2025-07-30 (1.1y ago). The live quote above, 44.5 keys, is 11% lower and last moved 17h 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: $116.41 — the lowest of 2 listings for the Terror-Watt effect when we looked on 2026-08-31 01:29 UTC (6d 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 44 keys, 34 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 Tyrant's Helm”, with no effect in the name — the effect comes from the individual listing.
