SCM Sale (Sale #19):

https://i.imgur.com/ci9H3Ki.png / https://i.imgur.com/e4dlMBr.png / https://steamcommunity.com/market/listings/440/Unusual%20Dark%20Falkirk%20Helm / https://backpack.tf/item/13876728231

$81.82 USD on 27th July. Keys were 2.13 USD this day. So 38 keys.

Buyers are 34.37, sellers 37.97

Sales @ 30, 32 33, 34, 34, 34, 38

Considering the amount of sales at 34 (3) as well as 3 more below 34, I think it's appropriate to take 34-38 here.
