Seller: https://backpack.tf/profiles/76561198447354401#!/compare/1583539200/1583971200

^I know that it says "obtained" but that's just because there isn't a loadable more recent version of the seller's backpack.

Sale 11:

C9 Buckaroo's hat + Mega Strike Russian Arms Race + '72 Bad Pipes + 2 pure, both taunts and Buckaroo are outdated so I'm going to exclude this one (I'm not sure what "use there" means but I've seen people use it in cases like this so could that be a proper way of doing this?)

15 pure, the amount is hard to see but I checked the histories of everything that was removed from the buyer's backpack and was able to trace 15 of the keys to this trade.

Sold with 5 pure and a rec for a Smoking Executioner, which is very much outdated, excluding (same here as with sale 13, could "use there" be the correct thing to do?).

Buyer: https://backpack.tf/profiles/76561198196894698#!/compare/1580515200/1580688000

The hat doesn't show in the buyer's inventory because he sold it so quickly but some of the keys can be traced to this trade and the dates match.

Marketplace.tf sales: (wasn't able to find histories on most of these)

https://marketplace.tf/items/tf2/30658;5;u91

Jan 30th @ 29.99$/1.7$ = 17.64 keys, rounding down to 17.5

Feb 9th @ 35.99$/1.7$ = 21.17 keys, rounding down to 21

Feb 10th @ 37$/1.7$ = 21.8 keys, rounding up to 22

Feb 12th and 13th (2X) @ 38$/1.7$ = 22.35 keys, rounding up to 22.5

Feb 21st, 23rd, Mar 8th (2X) and 9th @ 35$/1.7$ = 20.6 keys, rounding down to 20.5

Feb 24th @ 31.95/1.7 = 18.79 keys, rounding up to 19

Mar 18th @ 34$/1.7 = 20 keys

Mar 21st @ 34.65/1.7 = 20,38 keys, rounding up to 20.5

Mar 24th @ 37$/1.7 = 21.76 keys, rounding up to 22

Some histories:

https://backpack.tf/item/7015297669 It's most likely the history of either of the hats that were sold on Mar 8th for 35$ since the Marketplace bot changed on Mar 8th and it is now being resold on Marketplace.tf by a different person.

https://backpack.tf/item/4800066066 is the history of the one sold on Mar 18th

Sales:

4X 22.5, 22, 21, 6X 20.5, 20, 19, 3X 17.5, 17, 16, 2X 15.5, 3X 15, 14, 10?

Since there are many sales at 15 I'm going to include it in the range even though it is the current buy order price. Unsold @ 21 for 3 months so I'm calling anything over 20 an outlier.

Going with 15-20
