Looks like sold for a Green Confetti HKC + 3 keys, however that HKC was immediately flipped to a bot for ~39.55 keys (See bot buy orders https://gladiator.tf/listings/61a6b7f86728091eb7331df3, the history of the GC HKC https://backpack.tf/item/5357753073, and the fact keys matching buy order amounts came from same bot), so inclined to say this is essentially a pure sale for 39.55 + 3 = 42.55 ~ 43

Looks like sold the bat hat and used those keys + 19 other keys (the only other keys that left the bp) to immediately buy the HKC, the bot that got the bat hat was buying for ~22 (See https://gladiator.tf/listings/61a34b13dd7603e5220fd863, named Bubbashire at the time of sale), so this would mean it was bought at likely 19+22 = 41
