How the Gamma Case drops and opens
Only the rare pool still drops Gamma Case, first sold Jun 10, 2016, now, at a fraction of the old rate, so listings are dominated by earlier stock — currently from $2.84 across 28 marketplaces. As those copies get consumed, retired cases tend to reprice upward; the dated rotation log sits in the drop-pool registry. Drop-pool registry →
Budget $2.49 for the store key on every opening — Valve made keys untradable in 2019, so no market discount exists — plus the case, which marketplaces usually sell below the cost of waiting on a drop. Expected return per opening: $3.17 against $5.62, about 56% before selling fees. For one particular skin, the direct buy is the better trade; tiles above carry the comparisons.
From this page's data: 72 items priced live, the 9-day median case price moved -1.9%, Steam volume holds near 23 cases sold per day. All prices recompute with every data snapshot.

How much is the key?
$2.49 in the in-game store. Keys cannot be bought on the market or traded: the price is the same for everyone.
Is the Gamma Case worth opening?
The numbers say no: $3.17 expected return against $5.62 spent per opening (56%). If the goal is a skin rather than the thrill, direct purchase is cheaper.
Will the Gamma Case be discontinued?
It already rotated out of the active pool (rare pool as of our Apr 12, 2026 registry snapshot). It still drops rarely — cases never leave the game entirely. Drop-pool registry →
How do I get one without opening it?
Buying it is the practical route — from $2.84 across the markets in the table above. It no longer drops weekly.
Is opening cases legal in my country?
Loot-box rules differ by country: Belgium treats paid loot boxes as gambling and Valve disabled case opening there, while several other countries require odds disclosure or age gates. If opening is restricted where you live, buying items directly stays available. Responsible trading guide →
