Remind me to check my currencies.

Better fit, low end supported by a buyout.

Steam community market sale, was non-pro. Undetermined, since no one has one listed, so I can't check value on old sales.

Was using in my suggestion for the dahlia, but since it was an outlier there, and the counter that passed ignored it... here it is basically copy pasted.

+Energy Orb MW Black Dahlia (38-42)

+Aussie Black Box (17, nice parts but don't really matter)

+S Pro Machina (~11-12, buyer/seller 10.5/12, SCM ~$25-32, or ~9-13 keys)

I'm comfortable calling this an outlier.

Looks like SCM, and unknown either way.

Current listings: One has been up on classifieds at 28 for 19 days now, and outpost intermittently for the same amount of time:

Outpost:

Classified:

Not capping at this, mostly just because search functions for unusual weapons are still terrible everywhere.

Summary: 1 sale at 42 pure, supporting older sale at 40 pure, outlier at 21, and the one with the Dahlia. One reasonably-old buyout at 28 keys.

Since we're done with the Summer Sale and the Matchmaking update is finally happening, I'd like to give this a bit to see what happens with that listed one. Also, if anyone wants to look and see whether there are others of this that I missed, please do, but I didn't notice any additional sales on the items here that I'd found for the earlier version of this suggestion.

Update: The pistol that was listed at 28 keys sold twice this past week.

Item history: http://backpack.tf/item/4514543070

PISTOL SALE 1: Pro FT Isotope Masked Mender + Pro Blutsauger Kit (~3 keys at the time based on SCM)

http://backpack.tf/profiles/76561198099991573#!/compare/1468368000/1468454400

Estimate Mender at around 35-45 keys based on sales below. Sale is likely to cap at 28, since no unusual medi guns are listed at below 29 on classifieds or outpost, and the quickbuyer price on any generic unusual medi gun is 25 keys: http://www.tf2outpost.com/trade/28272545

Can't tell what the person who accepted the mender sold it for, unfortunately.

Still, if someone does want to try and track down a proper price for the Mender, here are a few possibilities:

Lots of the menders around, but not many sales this year.

One moved in June, looks like a big market dump:

http://backpack.tf/profiles/76561198086424277#!/compare/1465344000/1465430400

One sold in May, for another unusual medi gun plus stuff:

http://backpack.tf/profiles/76561198060486675#!/compare/1463184000/1463270400

~35 keys

Another sale, a day later: Sold w/ DP Killer Exclusive (~55) + 5 keys for Blizz Brown Bomber (outdated, using DedAndrei's buyout at 95)

http://backpack.tf/profiles/76561198060486675#!/compare/1463270400/1463529600

~40-55 keys, but pretty old

Another sale, April: 1:1 with otherwise-identical Energy Orb

http://backpack.tf/profiles/76561198052793694#!/compare/1460246400/1460419200

PISTOL SALE 2: Not clear.

Buyer:

http://backpack.tf/profiles/76561198128149670#!/compare/1466812800/1468800000

Seller:

http://backpack.tf/profiles/76561198099991573#!/compare/1468454400/1468540800

Long story short, looks like yes, it did sell at around 28, item value was probably higher than that but capped by the buyout.
