Buyout was 60 but this would likely end up being an outlier given the current unsold https://gladiator.tf/listings/6098a2ff7453ef19d732538d

Sales at 40, 44, 44, 45, 53, 53, 53, (60?)

There's a lonley buyer at 46 keys but that isn't enough to justify excluding the lower values since they're a common trading point, rest are at ~38 https://gladiator.tf/listings/60a89358a470edbdc04d7b2b

The sale at 60 can't be traced but given the unsold at 50 that would be a bit high anyway.

Gonna cut 40 off and go 44-53 with an outlier on each end since that's the most common trading point
