Community price on backpack.tf: 15.8–17.2 keys, last changed 2026-07-01 (2mo ago). The live quote above, 16.3 keys, is inside the community’s range and last moved 4h 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.

2 sold on the Steam Community Market in the 24 hours to 2026-08-29 15:47 UTC (7d ago), listed there as “Strange Australium Black Box”. 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.
