CS2 Cases

CS2 weapon cases are containers with a defined pool of skins and rare special items.

Check a case’s contents before opening it. Opening requires the matching key, bought in-game; keys bought since October 2019 cannot be traded or sold on the Steam Community Market.

The cheapest is Sealed Genesis Terminal at $0.04; the dearest, CS:GO Weapon Case at $96.11.

Rarity tiers and the real odds

Each case lists items by rarity color: Mil-Spec (blue), Restricted (purple), Classified (pink), Covert (red), and the special Rare item (gold — a knife, or gloves in glove cases). Valve publishes the official consumer-grade-equivalent odds: roughly 79.92% Mil-Spec, 15.98% Restricted, 3.2% Classified, 0.64% Covert, and about 0.26% for the gold rare-special slot. Every skin then rolls a wear (float) and has roughly a 10% chance to be StatTrak (souvenir cases differ — see below). Because the knife/glove odds are so low and the special slot itself contains multiple knife models and finishes, pulling a specific high-value knife is a compounding long shot. The expected market value of opening a typical case is below the combined cost of case plus key, which is the structural house edge.

Case types: weapon, glove, souvenir, and discontinued

Most cases are weapon cases whose gold slot yields a knife. Glove cases (Glove Case, Operation Hydra, Clutch, Danger Zone, Fracture, Snakebite, etc. — the ones flagged as glove collections) replace the knife slot with gloves. Souvenir packages are different animals: they drop to viewers during official Majors, can't be bought from the store as standard cases, and every item carries a tournament sticker and team/MVP context rather than StatTrak. Discontinued cases (CS:GO Weapon Case, eSports 2013, Operation Bravo, and other early containers) were pulled from the drop pool; their supply only declines, so prices climb over time and they behave like collectibles rather than consumables.

Which cases hold value vs. open for fun

Uncapped, currently-dropping cases trade for cents because supply refreshes weekly — these are pure lottery tickets, fine to open but poor to hold. Value lives in scarcity: discontinued cases, and cases containing a meta knife model (Karambit, M9 Bayonet, Butterfly) or a chase Covert skin that drives opener demand. The cheapest way to obtain a case is to simply play and collect weekly drops; the cheapest way to obtain the skin you actually want is almost always to buy that skin directly on the Market rather than open for it. Hold cases only if you believe Valve will discontinue the line or the contained items keep appreciating.
