Community price on backpack.tf: 13.77–17.11 ref, last changed 2026-04-26 (4mo ago). The live quote above, 18.55 ref, is 35% higher and last moved 1h 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 1h ago.
2 sold on the Steam Community Market in the 24 hours to 2026-08-27 10:22 UTC (9d ago), listed there as “Strange Aristotle”. 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.
