Added 10 pure for a Burning Noble (59.5, indate)

59.5 - 10 = 49.5

X = 50

You can't just make up prices if a hat is outdated. You have to make a mini suggestion of the samur-eye (basically a suggestion within a suggestion) to prove its value before you can use it. In this case the samur-eye has buyers at 56, which leads me to believe this is a high outlier.

$140 / $1.98 = 70.71 keys

Sold for 71 on mp.tf, there are more sales but I think shows the ballpark the samur-eye is in

There are sales at

~28 (AA)

32

50

~70 (samureye)

I think the AA sale and samureye sales are low and high outliers respectively, so somehow by some stroke of luck this suggestion is valid since there is an actual sale at 50.
