For some reason Gladiator.tf win't let me load the stas page for the keys at the time of the sale but the closest key suggestion to the sale is this one https://backpack.tf/suggestion/68018e3adb142963910ae8ee

3.02+0.04+0.1+0.09=3.25 keys

https://marketplace.tf/items/tf2/30615;5;u3179 Sellers at ~5.5 keys

https://steamcommunity.com/market/listings/440/Unusual%20Taunt%3A%20The%20Box%20Trot?filter=+Mystic+Fusion+ No sellers

Sales at 3.25 and 4.4

Although nothing actually counters the sale at 3.25 in the current state of things, the fact it sold in less than a day is to me a good indication that it was most likely a quicksell and probably shouldn't be the low end.

Going with 4.4 flat for now
