https://next.backpack.tf/classifieds/snapshots/Dead%20Presidents%20Big%20Elfin%20Deal/66d909abe8529bff242dde8f - Sellers at $17.99 or around 8.5 Keys and Buyers at 7.12 keys

Mindacos:

You could've used the $16.99 marketplace sale for the Elfin's mini:

https://marketplace.tf/items/tf2/652;5;u60 (~10 Keys at the time)

Not there's another sale, it's barely traceable but i'm confident it's useable here:

Sold for 7 Keys and some ref

https://backpack.tf/profiles/76561199125348079#!/compare/1721088000/1721174400

You could take the elfin at 7-10 for the mini.

12.3 + 8.5 = 20.8 Keys = ~ 21 Keys
