There are lots of sales below 122 keys, so that may be high. On top of that, looking at the item history, it's high likely that the same person who paid ~120 on mp.tf, sold it for half of that 3 weeks later. If that's the case, then 122 will be invalid entirely, so it would make no sense to price this based on a sale where someone paid 120 only to resell it a few weeks later for literally half of that.
