Rarity odds
Expected value
Assumptions
- Open cost = case price + key price.
- Skins within a tier are equally likely; StatTrak is an independent 10% roll.
- P(wear) = share of the skin's float range inside each wear band.
- Unpriced outcomes (2%) are excluded from the EV.
- Values are Steam Community Market snapshot prices, not net of market fees.

One opening costs $21.44 ($5.54 for the case plus $15.90 for the key), which ranks 19 of 42 cases from cheapest to most expensive. Its modeled expected return is $4.67 per opening, a modeled ROI of 21.8% (27 of 42 by ROI). That is an average over many openings, not a prediction for any single one.
Knives: Bayonet (6 finishes), Flip Knife (6 finishes), Gut Knife (6 finishes), Karambit (6 finishes), M9 Bayonet (6 finishes)
Each knife/glove finish is equally likely within the gold tier: about 0.0085% per opening (1 in 11,730) for any one specific finish (Doppler phases share their finish's odds).
