The Conga taunt had been sold in exchange for: 1 Snowfallen Warhood (49 keys), 1 Green Black Hole Barnstormer (60 keys), 1 Strange Bushman's Bristles (2 keys), and 3 pure keys. All totalling 114 keys.

https://backpack.tf/profiles/76561198258595884#!/compare/1602115200/1602374400 one of the sales was 60 keys.

Excluding all other sales due to them being too low for current buy orders. Also excluding my own sale for 114 keys and the sale for 44 keys due to them being outlier sales compared to the others. Going with 60 - 89 keys.

If you can find any other sales, let me know and I'll either add them to my data or make a 2.0 version with that data.
