Looks like 100 keys + Strange Collector's Professional Killstreak Classic (425, https://backpack.tf/suggestion/63599c4fc91abbb262064fe1) = 525 keys, looks to be under buyers at the time so potentially low/incomplete

https://gladiator.tf/time-machine?item=Sunbeams%20Pyromancer%27s%20Mask&at=2022-10-11T12:22:17.000Z - Lowest seller was 610 keys

Unclear, but looks like 781 keys leave, and they bought a Strange Smoking Bonk Boy the same day (for likely value between 138 - 162? https://gladiator.tf/time-machine?item=Strange+Smoking+Bonk+Boy&at=2022-10-10T06%3A40%3A00.000Z), 781 - 162 = 619 keys, we could probably assume this sale is between 525 and 630.

Remaining sales would appear pretty hard to mini (Credits Extazi):

Poisoned Shadows Little Buddy + 212 keys, Little Buddy seems to only have been gambled recently https://backpack.tf/item/2032459506, so unable to mini, taking buyers at ~224 https://gladiator.tf/time-machine?item=Poisoned%20Shadows%20Little%20Buddy&at=2022-11-10T16:40:24.559Z would give us 224 + 212 = 436 keys, looks to be on the low side.

Sticking with the first sale and rounding to 580 flat.
