Sold for a Circling TF Logo Data Mining Light + 7 keys. Seems rather high, considering the Hairpiece has sellers at ~16-18

Likely quicksold, and then used the keys to buy the c9 hat. You can see some of the keys in the buyer's backpack matching with the history of the c9 hat. Regardless, sold within a day so invalid.

SUMMARY

Sales: 15 / 15 / 15 / 15 / 15 / 16 / 16 / 16 / 16 / 17 / 17 keys

Sellers: 15 / 16 / 16 / 16 / 38 keys

https://gyazo.com/cdc20491886c24e3c23eb27a324266ee

With the constant stream of sellers at 16 keys and atleast 2 matured listings at 16 keys at the moment, I’d say 17 is an outlier. Going with 15-16 keys.
