https://marketplace.tf/items/tf2/5021;6

taking sales from last month for mini:

Oct 13: 7.29$

Oct 15: 7.29$

Oct 21: 9.99$ (high cuz of mp sellers)

Oct 22: 7.29$

Oct 25: 7.29$

Oct 27: 7.29$ (2x)

Nov 5: 7.29$

Nov 8: 7.29$

These are ~3.9 keys, that should be high because backpack.tf has active sellers at ~3.7k

Taking sales tracked by gladiator instead:

https://gladiator.tf/sales?item=Strange%20Professional%20Killstreak%20Your%20Eternal%20Reward

3 keys 28 refs = 3.47 keys

3 keys 18.88 refs = 3.32 keys

3 keys 24.44 refs = 3.41 keys are the ones that could be considered given the current sell and buy orders.

The average of these three sales is 3.4 keys so taking the YER as 3.4 keys, which makes the sale 16.4 keys = 16k
