-Sale 1 is more like 18 since these were added: http://backpack.tf/item/2898263914 http://backpack.tf/item/4492839337

-This sale: http://backpack.tf/profiles/76561197968625219#!/compare/1488499200/1488844800 is wrong, it actually sold for 25 pure: http://backpack.tf/profiles/76561198112612121#!/compare/1488412800/1488499200

-Your sale at 18 is actually a quicksell, PioTrex paid this price and flipped it in a day: http://backpack.tf/profiles/76561198269091267#!/compare/1487980800/1488067200

-1:1'd for a miami bear (needs mini): http://backpack.tf/profiles/76561198024660870#!/compare/1487980800/1488067200

I think you should include the 25 sale, rule out 18 as a quicksell, and look into the bear.

A little over 3 months old now, but supports 25 being the right price here.
