Kill-a-Watt Gauzed Gaze, 38 keys (Pool Party was not involved)

- KaW Gauzed Gaze has month and 2 month old sellers at 22 and 21 keys https://gyazo.com/7d01fcb101b9c02c9a07c6c16106ecd5

- https://marketplace.tf/items/30786;5;u56 April 10 sold for $38.00 / 1.77 = 22 keys (The $26.00 is quicksell price)

Taking the Gauzed Gaze at 21 keys, this sale is 59 keys.

Sales:

40, 51, 59, 85

Going with 40-60. 85 is a pretty drastic change, seems too high considering the last accepted price on this item was 40-50 keys. That being said, I don't see any reason to exclude 60, which is relatively close to 40 and 50.
