With that information in mind, the other low-craft would have to be less than half a key to change the value of this sale.

Buyer: http://backpack.tf/profiles/76561198074192315#!/compare/1462579200/1462665600

Not 100% sure if keys were involved here

Couldn’t get a mini on the Cranium or the Topi, however, assuming the keys were added, this sale would probably fit in the range.
