Updating a 9 month old price, currently 2 on the market, 19 in existence. 1 has a buyout of 3 buds, the other has no buyout. All the p.e. tricornes I will be using are clean according to backpack.tf histories.

Sales:

mine sold for ~3.1 after overpay (clean beams ze goggles, 3-3.7, 3.4-0.34, ~3.1)

unfortunately my previous trade offers are refusing to show themselves (error finding trade offers) and my inventory history will only tell me that I traded with Koala (for some reason it looks like trade offers don't show up properly on it), but you can check my backpack if it suits you; this was a 1:1 deal with no items added either side.

Offers:

http://www.tf2outpost.com/trade/16945182

moon capo: 2.7 after overpay (using original value, 5 month price)

hearts bonnet: 2.5/2.6 after overpay (price is in date)

2 pure

blizz tricorne + bubbling scopers

(old prices, original values with overpay are 1.6 + 0.9 = 2.7)

http://www.tf2outpost.com/trade/18136456

duped smoking beak (original value * overpay = 2.8, still fair to say that conservative estimate would put this above 2 even though it's duped)

All in all, considering the number of offers over 2, a rejected 2 pure offer, and sales at 3 and 3.1, 2 pure seems like an outlier.

Thanks for reading and voting; please do leave comments.

some extra proof now that Koala has put the one I sold to him up on the market, he declined an offer of 2 pure and and offer of a hearts raincatcher (2.4 after overpay, but an old price.)
