Community price on backpack.tf: 45.0 keys, last changed 2024-10-30 (2.0y ago). The live quote above, 15.4 keys, is 66% lower and last moved 3mo 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.
