$66.99 = 37 keys

Sold for Isotope Bomber Soul Scattergun (32 keys)

With 7 keys for Starstorm Fed Fighting Fedora

[[

The Fedora has no other sales.

The above Haunted Ghosts Runner's Warm Up + 7 keys sale (which would bring the Fedora to 40+ keys)

https://backpack.tf/profiles/76561198139684105#!/compare/1566000000/1566432000

https://backpack.tf/profiles/76561198091502579#!/compare/1565913600/1566000000

Bulk

But the Fedora is back for sale at 36 keys for 2 months, so it can't be over 40 keys and it give no valid data point for the Runner's Warm Up

https://gyazo.com/c36efd94ef37b812c438abbbb04795d1

https://marketplace.tf/items/tf2/780;5;u110

A sale for about 39 keys but it is about 2 weeks outdated and is still countered by the 36 key unsold.

So it would be an outlier for both sales. Overall, excluding it.
