Electrostatic Professor's Peculiarity
This price has not changed since 2026-08-31 22:09 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: 33.0–41.0 keys, last changed 2017-07-04 (9.3y ago). The live quote above, 24.8 keys, is 25% lower 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.
