untrace but snapshot suggests ~11.5k https://gladiator.tf/listings/615a41948b81e344f4352e87, which i guess buyer's compare supports, so 12k here.

https://backpack.tf/item/9555490136 - I don't think any sales here are usable

https://marketplace.tf/items/tf2/31153;5;u3010

Oct 16 sale for ~15k, in line with MP sellers

Sales:

9.5, 9.5, 12, 13*, 15

Two sellers below 15 so excluding that. Not sure if 10.88k buyer is active so I think 9.5k sales are valid here. I'll include 12 here to make a range, which rounds to 10-12k.
