I don't know about this one, https://backpack.tf/item/2877144876 was almost guaranteed to be the history for both sales, and if that is the case, it is almost guaranteed that the person who bought for 19 dumped for 14 2 days later.

Sold for a Ghosts Guilded Guard (35, outdated + no mini)

While the Guided is probably too high, it doesn't doesn't support the other sales.

I would leave this unupdated. Given who it sold to, I think it is unlikely it hits the market anytime soon either, so I don't think leaving this up has much merit.
