https://backpack.tf/item/7108222434 - 46 keys

https://backpack.tf/item/4147166115 - 50 keys

https://backpack.tf/item/4573767838 - 59 keys

Sales at:

35

40 (2x)

35 quicksold, excluding 35.

The $56 sale on marketplace went to a marketplace buy order. Excluding that one. Would end up being around 30 if used, which is lower than quickbuyers.

Seller of the $94 sale has a B/O of 50 keys for a different one currently listed, however, there are many factors that go against using this sale here. For example, there are cheaper sellers on marketplace, one of them listed on bp for 46, we have another marketplace sale that’ll end up being around 30-ish, and a pure sale at 35 that are already being excluded.

40 flat would probably work better here
