I don't have premium so some extra work will be needed to confirm these sales, sorry :(

The item in question: https://backpack.tf/item/8395948501

First sale I found on 15/1/2019, snowblinded winter wrap up for head hedge.

Seller (which shows three unusuals on that day, but other link shows 1 unusual given):

Buyer: https://backpack.tf/profiles/76561198052736868#!/compare/1579046400/1579132800

Second sale on 21/1/2019 for an amount higher than yours listed, although i'm not sure on any b/o. A head hedge + cloudy moon connoisseur's cap was sold for a stormy 13th hour connoisseurs cap.

Current seller on a cloudy moon cap @ 90, with the current one for sale not seeming to be the one used above: https://backpack.tf/stats/Unusual/Connoisseur's%20Cap/Tradable/Craftable/38

Seller link (although through info gathered pure/items are unknown if they were used in a trade): https://backpack.tf/profiles/76561198052736868#!/compare/1579478400/1579564800

Buyer (which seems to show pure may have been included):

https://backpack.tf/profiles/76561198140565712#!/compare/1579392000/1579564800

Im not sure what prices to take, as another unpriced hat was used and the cloudy moon cap is outdated, but my assumption is over 48 keys.
