42 keys and 3 spells

i can't find a mini on the knife, but one sold recently for $3.95 / $2.00 = 1.98 keys

https://marketplace.tf/items/tf2/901;11;kt-2

i mean i dont know why else it would less for that price

spelled botkiller knife = 2 keys

mini for freedom staff:

https://backpack.tf/profiles/76561198203650703#!/compare/1594252800/1594339200

https://backpack.tf/profiles/76561198803307242#!/compare/1594252800/1594339200

sold for victory lap (3.3 keys), then the victory lap sold on scrap (near ID of the victory lap matches to an item in the first compare link)

then the keys from the victory lap were used for something else

so basically, the spelled freedom staff = 3.3 keys

mini for frying pan:

https://backpack.tf/profiles/76561198203650703#!/compare/1594252800/1594339200

https://backpack.tf/profiles/76561198233340200#!/compare/1594252800/1594339200

8 keys

sale = 42, 2, 3.3, 8

rounding for 55 keys

which ends up buyers anyway. https://gyazo.com/bd445ab70c5f684ef3d011e6dd3b5fa9
