Honestly going with 22 keys flat here, I don't think it is completely fair to say 22 - 29 keys correctly represents the value of this item

22

Thanks Xerg:

https://gladiator.tf/listings/60194361a16390f43dab771d - likely sale at 24.5

https://backpack.tf/item/2618338271 + https://backpack.tf/item/2923026297 were likely bought for ~22-23 each

29 was pure, so I would prefer the full range of 22 - 29. Buyers are close to 23 now as well.

Taking 22 – 29 keys.
