listings arent sales. you need item sales for them to be valid. one sale also isnt enough to price it, multiple sales are required.

Good job on the first suggestion.

For the future be sure to add both sides of the sale/trade if possible.

(such as the Danto to Kolt trade for example)

I would also explain to the mods that although the Shellmet went into private bp, if we go by the key history of the Kolt trade, we can see it ended up in 2 amps' backpack (https://backpack.tf/u/76561198439410410) so we can understand where you got 69 from.

You can also exclude mannco.store sellers/sales since they cannot be used as proof anymore.

Otherwise, I think it should be fine, may have to stay open for a bit to see if the one on MP sells.
