http://www.tf2outpost.com/trade/17535955 added 2 keys for a ghosts pot 2.7 and with the keys 2.5 (even though it has a 5 month price that is outdated, there are still offers happening in the suggestion original range)

http://www.tf2outpost.com/trade/18336995 checked his bp and looks like it sold for 2 buds

http://www.tf2outpost.com/trade/16390848 and http://www.tf2outpost.com/trade/18249960 seems like sold for 2 buds/40 keys as well

http://www.tf2outpost.com/trade/17929291 seems like it sold for steaming muffs? outdated

http://www.tf2outpost.com/trade/15825823 sold for 2 here also

So with the research i've found, 1.5 seems like an outlier because no sales are happening at that range, BUT ALSO the 2.5 sale is effy b/c its outdated so the range is 2-2.2
