Also N&B pullover has moved 2 more times before the initial 53 key quickbuy for mixed offers totaling more than 53, so its not fair to give it a flat 53 rating.

Selling some items to STN buy orders and others to bp.tf buy orders, it is already above 50 keys in value even if you sell everything to the bots ( talking about the mixed trade in screenshot ). Selling taunts to the buy orders and taking Seared Sorcerer at bp.tf price:

Homerunner hobby unusualfier x 2: STN B/O @ 7 keys and in stock. 14 keys from just from B/O.

Dead Presidents Seared Sorcerer: 31 keys.

Conga: 2.8 keys.

Homerunner hobby: 2.01 keys.

Second rate sorcery: 4.5 keys,

Homerunner Hobby Unusualfier: B/O @ 7 keys STN.

Taking bp.tf price for the Seared Sorcerer and bot B/Os for taunts and unusualfiers, you get 61.4 keys in total in mixed. There is also a spelled hat with CC, buy orders for it are also at 3 keys. 64.4 keys in total. DE Seared Sorcerer also has a suggestion for 32 keys.

I believe the seller needed pure to buy an unusual KE, hence why he sold the unusual the same day after buying it. All in all not fair to price the hat at 53. 53-64.4 range gives out a 58.5k flat pricing, perhaps a resuggestion?

I'll go to sleep now, but here is the bp.tf history backing up the screenshot in case it is needed:
