Comment from Marty Birdman with extra sales:"

Modest mini (in-date at 75, but current price was a B/O drop so worth a mini anyway):

http://backpack.tf/profiles/76561198139171368#!/compare/1495584000/1495670400 - Sold w/ 2 keys for PE Brain Bowl, 65 - 2 = 63

Taking 63 for the Modest.

http://backpack.tf/profiles/76561198021055079#!/compare/1494547200/1494633600 - Sold for duped GE Hermes (mini at 40) + 10 pure, ~50

Hermes mini (credits to Sin, found it on his Phononaut suggestion):

http://backpack.tf/profiles/76561198258101857#!/compare/1494288000/1494374400 - Sold for Smoking Airdog, Smoking Baker, ~7.5 in sweets, calling this 40

http://backpack.tf/profiles/76561198118157202#!/compare/1494547200/1494633600 - Sold for PE Physician, 62 (sold within a day by the trader who paid the Hermes, hence the misleading compare - histories match the Cotton)

Scrapprehensive sold under a week, lowest current seller is asking for 70, only 3 days old, lowest mature seller wants more than your highest sale - http://imgur.com/a/GdGfo + http://www.tf2outpost.com/trade/28118131

36 is countered by buyers, leaving valid sales at 50, 50, 52, 62, 63, 70, and 75. Polled some other moderators, agreed 50-63 would be best here - sale at 70 is bulky & not the best to use, and sale at 75 seems poorly supported by comparison to the rest, but the higher sales also support including a high end here. Please re-suggest at 50-63."
