Outlier. When taking the Jester and Bandito as their lowest seller (48 / 14) the sale would turn out at 34, which is too high here.

SALE #3 = 15 keys

http://backpack.tf/profiles/76561198267189538#!/compare/1486944000/1487030400

Sold for 15 keys. Took about 3 weeks so not really a quicksell.

SALE #4 = invalid

http://backpack.tf/profiles/76561198227232564#!/compare/1491350400/1491436800

Appears to have been quicksold for 13 keys. Taunts were not included. 13 keys is going to be very low here.

SUMMARY

Sales: 15 / 23

Sellers: 18 / 19 / 22

23 key is an outlier. Going with 15 keys as per Mindacos advice.
