This price has not changed since 2025-11-10 00:14 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: 220–270 keys, last changed 2025-03-25 (1.6y ago). The live quote above, 270 keys, is inside the community’s range and last moved 12mo ago.

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.
