Didn't notice you already made a suggestion for the hat while I was making it, so here is my research. I think the range should be 29-35 keys, and here's the reason:

sale 1:

buyer: https://backpack.tf/profiles/76561198055622215#!/compare/1581897600/1581984000

seller: https://backpack.tf/profiles/76561198120672630#!/compare/1581897600/1581984000

Hg bumble + Aces spartan (14.5k) for robo brainbucket (55.5k)

value: 41 keys

sale 2:

buyer: https://backpack.tf/profiles/76561198084130751#!/compare/1581033600/1582070400

seller: https://backpack.tf/profiles/76561198055622215#!/compare/1581984000/1582070400

sold for c. heart condor cap (unpriced)

value: unknown

sale 3:

buyer: https://backpack.tf/profiles/76561198396190709#!/compare/1584403200/1584662400

seller: https://backpack.tf/profiles/76561198084130751#!/compare/1584576000/1584662400

sold for 35 keys pure

value: 35 keys

sale 4:

buyer: https://backpack.tf/profiles/76561197965601027#!/compare/1594339200/1596326400

seller: https://backpack.tf/profiles/76561198396190709#!/compare/1588377600/1590105600

Not sure about this: buyer shows it sold for cloud 9 hallmark(22 keys) + cloud 9 execution(17 keys), but seller shows it sold for 35 keys pure.

Both have a total value of 35 keys so I'll take that, but if anyone can help me out explain this to me that would be great.

value: 35 keys

Marketplace:

https://marketplace.tf/items/tf2/31085;5;u8

1x @ $25.06 / $1.88 = ~13.5 keys

1x @ $57.99 / $1.99 = ~29 keys

Summary: Ignoring the 13.5 key sale and rounding the first sale to 35 due to overpay in items, the range should be 29-35 keys
