Average across the 60 of 60 finishes in this case’s gold pool we hold a price for, hit 0.26% of the time

Method: within a rarity tier every skin drops with equal probability, and within the gold tier every knife or glove finish the case can actually drop does; each outcome is valued at its cheapest listed wear across markets, with StatTrak folded into non-gold drops at the published ~10%. Because every outcome is taken at its cheapest wear and those are buyer prices rather than what a seller banks after market fees, the figure is rough in both directions at once. Prices updated Aug 27, 2026. The same numbers, computed the same way but published only where every outcome carries a real price, are on our case RTP breakdown. If you want a specific skin, trade-ups or buying it directly are almost always cheaper than opening for it.
