Right now it goes for $432 to $888 across 7 marketplaces — a 105.5% spread. Liquidity is low: just 2 sales a day. An item like this can sit for weeks, and an attractive listing price does not mean anyone will pay it.

We track 5 wear levels of this skin. The cheapest is BS at $406, the priciest is FN at $1 147 — a 2.8x difference for the very same artwork, the wear is all that changes. Over the past 30 days the price stayed between $426 and $1 019, and it is now 7% lower than a month ago. The all-time high is $1 019, the low is $426. Float for this skin runs from 0.0 to 1.0 (the range of the whole skin, not of a single wear): the lower the number, the cleaner the finish, and copies at the edge of the range are valued separately.

The skin comes in all five wears, from Factory New to Battle-Scarred, so the choice is always between a clean finish and a lower price. For Case Hardened the price depends on how much blue the finish shows: copies with a large blue patch (a "blue gem") cost several times more than ordinary ones, and the paint seed decides it, not the wear.

Marketplace prices

★ M9 Bayonet | Case Hardened (Well-Worn) is listed on 6 marketplaces. The most you keep is on steam: $854 minus a 15.0% fee leaves $743 net. The least you keep is on lis: $432 minus a ~9.7% fee leaves $390. The $352 gap comes from both different listing prices and different fees; a large gap usually means the listings differ in wear or condition, so check the item itself before selling. If you need cash out rather than Steam wallet funds, the best option is skinport, $503 net.

Fees are the marketplaces' standard seller rates; Steam's 15% is charged on the seller's amount, so the net is the price divided by 1.15. Volume discounts, promo codes and regional specifics are not included, and Steam proceeds stay in the Steam wallet.

A rate marked with a tilde (~) is our own estimate, not a published figure: it is derived by comparing the marketplace's own buy and sell prices. The real cut varies from item to item and is usually worse on cheap listings.
