This price has not changed since 2025-11-10 01:19 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: 205 keys, last changed 2022-04-14 (4.4y ago). The live quote above, 206 keys, is the same and last moved 10mo 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: $800.00 — the lowest of one listing for the It's a Mystery to Everyone effect when we looked on 2026-08-31 01:30 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 206 keys 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 Duck Billed Hatypus”, with no effect in the name — the effect comes from the individual listing.
