CS:GO Weapon Case
Released Sep 20, 2013
Drop odds
Every standard case uses the same rarity distribution, so opening one is mostly a Mil-Spec lottery: red and gold pulls together account for less than 1% of openings. Roughly 1 in 10 drops comes out StatTrak™.
| Rarity tier | Skins in tier | Tier odds | Odds per skin |
|---|---|---|---|
| Mil-Spec Grade | 3 | 79.92% | ~26.640% (1 in 4) |
| Restricted | 3 | 15.98% | ~5.327% (1 in 19) |
| Classified | 2 | 3.2% | ~1.600% (1 in 63) |
| Covert | 1 | 0.64% | ~0.640% (1 in 156) |
| Rare Special Item | 65 | 0.26% | ~0.004% (1 in 25,000) |
Source: rarity odds disclosed by Valve for case openings in China. Opening also requires a key bought in-game, so factor that cost in before chasing a specific skin.
Is opening worth it?
Opening this case costs about $117.71 (case plus key) and the contents are worth $63.44 on average, so you statistically get back 54 cents on the dollar. Buying the skin you want directly is almost always cheaper than chasing it in drops.
Method: official tier odds times the average median market price of each skin across its wears (69 of 74 items have live listings, prices from 2026-07-14). StatTrak upgrades are ignored, which makes the estimate slightly conservative.
Rare Special Items (knives & gloves)
