https://backpack.tf/item/1776071524

Without the Scorching Chapeau, this’ll end up being 547.5. Should be safe to assume this sale would end up being around 650-700.

Also worth noting that the only marketplace sales we have to work with are both below current marketplace buy order price.

It is worth noting that during the creation of this suggestion, DX and Bull were undercutting each other for a while. I hadn’t screenshot any of the listings other than DX at 500, but Bull’s price dropped as low as 599 (from 649 and 699, not sure about the other times). Bull’s listings were 1 key less than DX’s, meaning DX was listed at 600, 650 and 700. Again, don’t remember what they were at prior to this. On top of this, after DX listing at 500, it took at least a week to sell, if i remember correctly. With all this in mind, I’m not sure if excluding 475 is a good idea. However, the number of sales for much higher seem to outweigh the one sale at 475. I will exclude 475 for now, unless told otherwise.

Excluding 836 and 850, given the months unsold at 800. Also worth noting that both these sales are the Scorching TC sales. Given this, it may be a better idea to use these sales as minis for the duped Scorching TC instead.

Going with 685-770.

https://backpack.tf/profiles/76561198043991016#!/compare/1539648000/1539734400 appears to have been bulk for cash, currently listed for around $1400 on marketplace.
