Don’t know the B/O for this, it obviously would’ve been quite a bit low than what this sale would amount to. Excluding.

7 keys + half a key in metal match (keys on the buyer’s end), but I’m fairly certain there were more involved, given current buyers. Very likely that some of the stuff on the buyer’s end sold for pure, then went towards the hat.

Doesn’t show up on bot.tf, so I’m assuming the bot owner withdrew it and sold to the buyer’s buy order or something. Buyer’s end shows many keys going to the bot’s backpack, so they probably bought multiple items from them.

No sales on the Vanquisher, can be used there instead.

Sales at:

10.5 (2x)

No current sellers.

Average price of the sales is below 10, so we round the the nearest 0.5 keys.

Taking 9-10.5.
