Taking that in the Steam Community Market, Steam and TF2 take like 14% of all the sells, and the sell orders of the Breadcrab are close to $ 9.45, so 9.45 - (14% of it) = $ 8.13 = 4.36 keys according to Calculator.tf, and the currently buy order is worth $ 8.21 = 4.4 keys
So my suggestion is that, the price of the Breadcrab is worth a little more than 4 keys.
You'll need some more proof for the low end, 4.2-4.37 both seem to come out of nowhere. The Steam Community Market is generally going to be an inflated price, so it's often only used as supporting proof. This post goes pretty in depth if you would like to suggest:

Please round prices to the nearest 0.05 keys.
You need to round your values to the nearest 0.05 keys and you can't use sellers as a high end without sales
