This price has not changed since 2026-10-02 00:08 UTC. It reflects the last observed trade rather than current market value, and this page is excluded from our sitemap for that reason.
Community price on backpack.tf: 16.0–19.0 keys, last changed 2019-11-24 (7.0y ago). The live quote above, 23.5 keys, is 47% higher and last moved 1mo 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: $74.96 — the lowest of 2 listings for the Kill-a-Watt effect when we looked on 2026-10-30 01:35 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 23 keys, 32.55 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 Dark Falkirk Helm”, with no effect in the name — the effect comes from the individual listing.

The key axis converts at today's rate. Prices are recorded in metal, so a line that is flat in keys followed the key rate rather than standing still.
