Not including this sale because it's somewhat old and the buyer sold it for less (I'd imagine, since this went to a quickbuyer who then sold for 16 Keys).

https://marketplace.tf/items/tf2/30816;5;u3022 - Sold for $45 when Keys were ~$1.84 each and $50 when Keys were ~$1.83 each

45 / 1.84 = 24.46, which rounds to 24 Keys

50 / 1.83 = 27.32, which rounds to 27 Keys
