| Classified | 3.20% | 3 | 1.067% |

| Mil-Spec | 79.92% | 7 | 11.417% |
Odds are Valve’s published container probabilities; each item within a tier is equally likely, so per-item odds are the tier chance divided by the number of items in that tier. StatTrak appears on roughly 10% of non-special drops. Souvenir and other container types can differ.
Expected Value Analysis
Against a $5.10 cost (case $3.75 + key $1.35) — you recover 72% on average
79.92% of openings return a low-value Mil-Spec — the distribution, not bad luck, drives the result
Average across 60 priced finishes in the gold pool, hit 0.26% of the time
Method: every skin in a tier drops with equal probability; tier value uses each skin's lowest live marketplace price (17 of 17 contents priced, 60 of 60 gold-pool finishes priced). StatTrak upgrades (~10% of non-gold drops) and wear-tier variation are not modelled, so the true return sits slightly above this estimate. If you want a specific skin, trade-ups or buying it directly are almost always cheaper than opening for it. Prices updated Jul 13, 2026.
