Community price on backpack.tf: 200 keys, last changed 2024-12-27 (1.7y ago). The live quote above, 53.0 keys, is 73% lower and last moved 12d 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: $636.45 — the lowest of one listing for the Shrieking Shades effect when we looked on 2026-09-01 01:42 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 53 keys, 1.77 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 Bone Cone”, with no effect in the name — the effect comes from the individual listing.
