Zipel "confirming" prices didnt really change. This part is iffy. https://imgur.com/HPdKBH2

Xergoyf's response https://imgur.com/BxoJ4Po

Looks like 10.29 is my key price.

158,998/10.29 = 15,451.70. Rounding to 15,450

It's a horrendous range, yes, however looking at the Burning flames Noh Mercy: https://backpack.tf/suggestion/5d845051d3817225645fc3e6

A gargantuan range was allowed because:

"Such ranges are a last resort - normally, when the sales are this discrepant, the hat is left outdated until it resells.

The situation here is tricky since the hat was already updated based on one of the two sales. What would support updating rather than leaving outdated as a whole is that both sales were above its old value, indicating an update is actually called for. With no clear indicator which of the sales would be the outlier, the range offers a wonky solution for the issue that the sales are actually way discrepant, but a solution nonetheless." -FoamyTheFearsome

Granted, that was 2 years ago? But hey, I'll give it a shot.
