Suggestion: Green Black Hole Hustler's Hallmark at 400–620 keys

Should try including any other unusable sales as it makes it easier and more readable regardless I'm going to leave the new sales and those you did not include here

Bulk in between Sale 2 and Sale 3

Going to double check but pretty sure since we have three sales now at 400ish range 620 would count as an outlier but will come back to make sure of it!

And just confirmed that yeah 620 now is an outlier, should be fine to resuggest this at 400-430!

One of those bulk sales looks usable.

GBH Hustler's Hallmark + Gangreen Footprints Spelled Cloudy Moon Sergeant's Drill Hat + 600 keys (keys confirmed on buyers) traded for a Knifestorm Tyrant's Helm

Knifestorm Tyrant's Helm is priced at 1800-2000 keys. I'll take the average 1900.

Gangreen Footprints Spelled Cloudy Moon Sergeant's Drill Hat Mini

Sale 1

https://backpack.tf/profiles/76561198124904264#!/compare/1713484800/1713571200

https://backpack.tf/profiles/76561198094964657#!/compare/1712793600/1713571200

Sergeant's Drill Hat + 50 keys traded for a Cloudy Moon Swagman's Swatter (450) + Frostbite Vintage Tyrolean (400).

Cloudy Moon Swagman's Swatter is priced at 450 keys.

The Frostbite Vintage Tyrolean has only one other usable sale:

https://backpack.tf/profiles/76561198124904264#!/compare/1712793600/1712880000

https://backpack.tf/profiles/76561198440460554#!/compare/1712448000/1712880000

400 keys.

This would price the Gangreen Footprints Spelled Cloudy Moon Sergeant's Drill Hat at 800 keys.

Returning to that bulk sale.

GBH Hustler's Hallmark + Gangreen Footprints Spelled Cloudy Moon Sergeant's Drill Hat (800) + 600 keys traded for a Knifestorm Tyrant's Helm (1900).

This would price the GBH Hustler's Hallmark at 500.

Should I include this sale in the resuggest? Does it have any impact on whether the 620 sale is an outlier or not?

It would not be usable because it is a bulk sale as stated, if the unusual is worth less than 50% of value in the trade it shouldn't be considered to price the item in question unfortunately!

Gotcha! I'll resuggest with the 400-430 range.
