Marketplace.tf sale: https://marketplace.tf/items/tf2/167;5;u3009

October 19: 2 @ $14.44/1.87=7.72 ~7.5 keys

October 20: $14.44/1.87=7.72 ~7.5 keys

October 23: $14.44/1.86=7.76 ~8 keys

October 27: $14.99/1.85=8.1 ~8 keys

We have 6, 7.5, 7.5, 7.5, 8, 8

6 is a bit low looking at buyers so excluding.

8 is gonna be a bit high because a seller at 7 has been trying for a month https://bot.tf/stats/listings/4RD5EG39. They also had it listed at 8.5 and 8 but didn't successfully sell it

7.5 is more consistent than 8, excluding 6 and the fact a seller at 7 tried for a month supports excluding 8 too.

Seller at 7 is gone now but sale isn't traceable

Listening to Blaze, going 7.5 flat
