About the Spectrum Case
The Spectrum Case holds 17 weapon skins across four rarities, plus a rare special pool of 30 knives. The most valuable regular skin is the AK-47 | Bloodsport, listed from $102.81 to $138.89 depending on wear. It costs $18.68 to open: $3.12 for the case and $15.56 for the key.
Because the rarity odds are fixed, the Spectrum Case comes down to its list of skins. A knife or gloves drop is 0.26% per opening, about 1 in 385; open it 100 times and the chance of at least one is 23%. Want to see how that feels before paying? Try the Spectrum Case in the free case simulator, which uses these exact odds, then compare it with every other case on the case odds page.
Spectrum Case odds by rarity
Valve's disclosed rates are the same for every weapon case. What differs per case is how many skins share each tier, which sets the chance of each individual skin, and what those skins are worth.
| Rarity | Chance | Skins | Chance per skin | Average skin value | Adds to EV |
|---|---|---|---|---|---|
| Mil-Spec | 79.92% | 7 | 11.417% | $0.54 | $0.43 |
| Restricted | 15.98% | 5 | 3.196% | $1.93 | $0.31 |
| Classified | 3.20% | 3 | 1.067% | $14.35 | $0.46 |
| Covert | 0.64% | 2 | 0.320% | $109.98 | $0.70 |
| Rare special item | 0.26% | 30 | 0.009% | $252.63 | $0.66 |
| Total | 100.00% | $2.56 |
Expected value = sum of each rarity's chance times the average value of its skins. Skin value is the lowest listing at each wear, weighted by how much of the skin's float range falls in that wear, with the 10% StatTrak roll included. Wears with no live listing are left out of the average.

Knives and gloves are the rare special pool: the case never shows which one until it opens, and the pool's average uses the average lowest listing across every item in it. See current knife prices on the cheapest knives page. “No listing” means nothing is on sale right now.

FAQ
How much does it cost to open a Spectrum Case?
$18.68 at the prices of 10 November 2026: $3.12 for the case plus $15.56 for the key. This case uses its own key, which Valve no longer sells in its store, so the key price is the lowest player listing (153 listings).
What are the odds in the Spectrum Case?
Valve's disclosed rates apply: Mil-Spec 79.92%, Restricted 15.98%, Classified 3.20%, Covert 0.64% and a rare special item (knives) 0.26%. With 7 Mil-Spec skins, each one is about 11.42%.
What is the best skin in the Spectrum Case?
Among the regular skins, AK-47 | Bloodsport is the most valuable, listed from $102.81 to $138.89 depending on wear. The rare special pool (knives) holds the biggest prices, up to $1,939.61, at a combined 0.26% chance.
Is the Spectrum Case worth opening?
On average, no: one opening is worth about $2.56 in lowest-listing prices against a cost of $18.68, a return of −86%. Selling on Steam takes a 15% fee on top, and the average is carried by very rare drops, so most single openings return less than they cost.
Can I open the Spectrum Case for free?
Yes, in the case simulator. It uses this case's real contents, Valve's disclosed rates and the prices on this page, and it spins a reel for each opening. Nothing is bought and nothing is added to a Steam inventory. You can open up to five at once and the session tally shows what the cases and keys would have cost.
Do StatTrak skins drop from this case?
Yes. Any skin that exists as StatTrak has a 10% chance of being StatTrak when it drops. The expected value figures include that.
