How is this still priced at 7.75 Keys, wut?

Gladiator stats:

https://gladiator.tf/sales?item=Unusual%20Horseless%20Headless%20Horsemann%27s%20Headtaker

Ignoring the random 19 Key and 30 Key trades (assuming spelled). Past 30 Days range is 9 Keys 25 Ref - 12 Key.

Sold Jan 21st on mannco store at 40 USD, mannco keys 1.90 at time of suggestion:

https://mannco.store/item/5826

40 / 1.9 = 21.05 Keys.

Well out of the norm, doesn't match trade stats or buyer/seller range.

*Adding in marketplace sales noted by Offline. Thought I put them in but apparently not lol*

Marketplace consistently sells this for $26.90 to $27.99, which ends around 12.5-13 keys, but with the number of sellers at 12, I think 10-12 is already a good range.

This looks like a sale of an entire backpack or a bot dump:

https://backpack.tf/profiles/76561198833491066#!/compare/1609286400/1609891200

That should be pretty much all the trades I can find, if I missed any then my bad. Might have missed 1 or 2.

Only 3 sales were below 10 Keys; 9 Keys 25 Ref, 25.66, and 45 Ref. So I am rounding up to 10 Keys as minimum range.
