The seller doesn’t appear in the history because they put it on marketplace before it was scanned in their backpack. Given the seller’s experience with Holy Grail taunts (especially unpriced), and the fact that 15 keys in the buyer’s side happen to have gone to them, it seems pretty clear that this is the case. If memory serves me right, they originally had the taunt listed on marketplace for $29.99, but I can’t confirm this.

= 15 keys
