I got offer for 17 pure for this hat, but the guy cancelled it in ~4 minutes and probably sold his hat to a bot for the same value.

Appears only 7 keys. I think he spent around 9-10 keys to buy australium ambassador.

https://backpack.tf/profiles/76561198324473963#!/compare/1551571200/1551657600 -> showing only 4 keys, but you can see they came from Rich Chigga

Total: 17, 19, 20

Not going to include 17 and leaving with 18-20. Previous suggestion is still indate.
