Buyout was 8.5 keys https://bot.tf/stats/listings/4P0LXER5

Sales 19-21)

https://marketplace.tf/items/tf2/1015;5;u3001

$5 - below buyers

$19.99 / $1.87 = 11 keys

$10 / $1.84 = = 5.5 keys

Sales:

5.5, 7, 8, 8, 11, 11 and 12

Calling 5.5 low due to buyers

Calling 11 and 12 high due to sellers, most noticably the 3 month unsold at 9 keys. The 12 key sale is questionable given the buyout. The $16 seller also suggests $20 is high

Thanks =)
