The cheapest legal contract, worked through
Ten copies of UMP-45 | Briefing in Battle-Scarred at €0.12 each make the cheapest Mil-Spec Grade contract here: €1.20 in, one Restricted skin out. The cheapest Battle-Scarred copy sits at the worst float of its band, 1, which is 100 percent of the way up that skin's own range, and that position, not the raw float, is what maps into each outcome's range. At that float the outcomes land in Well-Worn to Battle-Scarred.
Priced at those wears, none of the 5 outcomes we can quote nets more than the €1.20 ticket after the venue's fee. They run from €0.81 to €0.97.
That's the calculator's arithmetic on the cheapest listing, not a pick; price your own ten in the trade-up calculator.

Mixing in other collections
The ten inputs don't have to come from one collection: each input hands its own collection a tenth of the odds. Five Mil-Spec Grade inputs from here and five from The Harlequin Collection split the contract 50/50, so each of this collection's 5 outcomes drops to 10.00%, and The Harlequin Collection's 2 outcomes share the other half.
