Aztec 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 Aztec Collection each possible result below has the chance shown; with 5 of 10 inputs from here, halve it.
Consumer x10 → Industrial: 50% each (float range in grey)
- AK-47 | Jungle Spray 0.06–0.80
- M4A4 | Jungle Tiger 0.06–0.80
Industrial x10 → Mil-Spec: 100% each (float range in grey)
- Tec-9 | Ossified 0.00–0.08
- Mil-Spec is the highest rarity in the Aztec Collection. Its Mil-Spec skin can come out of a trade-up but can't go into one: the game only accepts inputs whose collection has a skin one tier higher.
StatTrak: none of these skins exist in StatTrak, so every trade-up into this collection uses non-StatTrak skins.
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.
