Right now it goes for $0.030 to $0.070 across 5 marketplaces — a 133.3% spread. Liquidity is low: just 1 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 FT at $0.030, the priciest is FN at $0.280 — a 9.3x difference for the very same artwork, the wear is all that changes. Over the past 30 days the price stayed between $0.020 and $0.050. The all-time high is $0.130, the low is $0.020. Float for this skin runs from 0.0 to 0.5 (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.
