Trade-up ladder: this collection only
10 items of one rarity from this collection guarantee an output from the next tier up. Costs use the cheapest wear of the cheapest input; output value is the tier average.
| Input | Cost | Possible outputs | Avg output | EV?Expected value of one trade-up: the tier-average output minus the cost of 10 inputs. Wear carries over from your inputs, and collection ladders are rarely profitable at open asks. |
|---|---|---|---|---|
| 10× Mil-Spec | $32.30 | 5× Restricted | $15.90 avg | -51% |
| 10× Restricted | $119.21 | 3× Classified | $59.55 avg | -50% |
| 10× Classified | $480.70 | 2× Covert | $210.81 avg | -56% |
