This price has not changed since 2026-10-02 00:09 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: 3.55–5.11 ref, last changed 2026-04-25 (6mo ago). The live quote above, 3.66 ref, is inside the community’s range 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.
0 sold on the Steam Community Market in the 24 hours to 2026-11-02 03:53 UTC (3d ago), 22 over the last 7 days, listed there as “Strange Head Mounted Double Observatory”. That is a different market from the prices above: Steam takes roughly 15% and pays out in Steam wallet funds rather than cash, so its prices sit above what an item realises elsewhere. Volume is unavailable for unusuals — Steam’s name for one leaves out the effect, so every effect shares a single listing.
