The cheapest legal contract, worked through
Ten copies of FAMAS | Macabre in Battle-Scarred at €2.12 each make the cheapest Mil-Spec Grade contract here: €21.20 in, one Restricted skin out. The cheapest Battle-Scarred copy sits at the worst float of its band, 0.6, 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 Battle-Scarred.
Priced at those wears, none of the 5 outcomes we can quote nets more than the €21.20 ticket after the venue's fee. They run from €8.98 to €19.01.
That's the calculator's arithmetic on the cheapest listing, not a pick; price your own ten in the trade-up calculator.
