2021 Vertigo Collection trade-ups
A trade-up contract takes 10 skins of the same rarity and returns one skin of the next rarity, from the collections of your inputs. Valve doesn't publish the exact odds; calculators and most guides use this model: each input gives its own collection a 10% share, and inside a collection every skin of the next rarity is equally likely. On that model, with all 10 inputs from the 2021 Vertigo Collection each possible result below has the chance shown; with 5 of 10 inputs from here, halve it.
Consumer x10 → Industrial: 25% each (float range in grey)
- Glock-18 | Red Tire 0.00–0.55
- PP-Bizon | Breaker Box 0.00–0.44
- SSG 08 | Carbon Fiber 0.00–0.12
- UMP-45 | Mechanism 0.00–0.49
Industrial x10 → Mil-Spec: 25% each (float range in grey)

- The Covert skin at the top of the 2021 Vertigo Collection can be reached by trading up Classified skins. The 5-Covert knife and glove trade-up gives a knife or gloves from the collection of one of its inputs, and this collection has none, so its Covert skins don't work there.
StatTrak: none of these skins exist in StatTrak, so every trade-up into this collection uses non-StatTrak skins.
Souvenir versions of 2021 Vertigo Collection skins come from souvenir packages; the game data lists 6 packages that can contain them, for example the Stockholm 2021 Vertigo Souvenir Package. Since the May 2026 update Souvenir skins can go into trade-up contracts, mixed with normal ones; the Souvenir status is removed and the result is a normal skin.
The float of the result depends on the floats of your inputs and the result's own range: see how the trade-up float is calculated and how trade-up contracts work.
