Pickel Mini:

Sold for Searing Officer’s Ushanka (mini at 23.5 below)

No outpost

Seller: http://backpack.tf/profiles/76561198053727332#!/compare/1473379200/1473465600

X = 24

Given the Searing Ushanka mini isn’t the greatest, as it’s kinda all over the place, I added a little supporting proof for the Pickel:

Bought from scrap.tf for Terror-Watt Titanium Tyrolean (15) + Miami Nights Berliner’s Bucket Helm (outdated, shouldn’t be any less than 15 due to the buyer at 14)

No outpost (obviously)

Seller: http://backpack.tf/profiles/76561198135388328#!/compare/1473120000/1473206400

Buyer: http://backpack.tf/profiles/76561198135880720#!/compare/1473120000/1473206400

Sale would be at least 30

Using this sale as support for the Pickel, rather than setting an exact price on it.

This should prove the Pickel to be more than 23, which would cap Sale 2 at the B/O of 23.

Sales at:

25

Purchased this for 18 keys via my buy order (which, at the moment, is closed due to lack of keys)

Going with 23-25

I had absolutely no idea that the 23 key seller existed during the 12 days it had been up, lol. Luckily, it benefits me, because I was a little worried about the low-end of my suggestion being insufficient, with all the confusing sales and minis, but this seller should make the low-end a little more stable
