28 keys (credit to Erik for the screenshot https://imgur.com/ScYsoBo), buyer listed it on MPTF

Sales:

20, 28 (x2), 34

Sellers:

BPTF - https://imgur.com/3M7veCu 35 keys (2 months), 45 keys (4 months)

MPTF - https://marketplace.tf/items/tf2/1172;5;u3200 $59.99 (~30 keys)

The one on MPTF, judging by the history, has only been there for around 2 weeks. Cash wise it's only $3.01 less than the sale so I don't think it's reasonable to exclude 34. 20 feels low with buyers at ~20 keys, plus I'm not convinced it's the whole sale.

Going with 28-34 keys
