46Keys

The person who paid 46 Keys dumped this to the Kaguya bot for what has to be much less, but it's not clear exactly how many Keys that was.

https://backpack.tf/profiles/76561198272148004#!/compare/1744848000/1745625600 - Some of the Keys they got for the Puffy were used for the Noir

https://backpack.tf/profiles/76561199072654974#!/compare/1745452800/1745539200 - The Noir was sold to them for 27 Keys + 22 Refined

https://backpack.tf/item/12865743392 - Several of those 27 Keys have Kaguya in the history just before Scrapyard

The Puffy was then quicksold with a Phantom Plague Second-Hand Headwear for 73 Keys, but I don't know the breakdown of how many Keys were for each.

https://scrap.tf/auctions/ZLF1GM - The Puffy was then auctioned off for 32 Keys after being listed for a little bit on backpack

32 flat would be better here.
