Bulk for a Roboactive Veil

Some more Vive sales:

https://marketplace.tf/items/30422;5;u108 - 50 & 75 keys, 50 doesn't really seem like a qs judging by histories: https://backpack.tf/item/5195035202 + https://backpack.tf/item/5185658718

https://backpack.tf/profiles/76561198133540930#!/compare/1510617600/1510704000 - Scorching Toque (mini at 52) + ~6 keys, 58 keys total

Toque mini: https://backpack.tf/profiles/76561198133540930#!/compare/1511049600/1511222400 - CV Conquistador (39.5), Peace Tavish (micro at 12.5), and ~4 keys of sweets, 56 total

https://imgur.com/a/Q10Ns - Sellers at 46 & 48 - 48 is mature so we'll take that one and go with 48-56.

Tavish micro: https://imgur.com/a/ZIR6z - 1 week at 12.5, taking 12.5

So sales are 50, 58, 69, and 75. Quite a lot of variance there, and plenty more sales across the board involving different outdated/unpriced hats. Would use the midpoint (non-MP) sales for the Vive's mini range, putting it at 63.5.

Also, it was 12 keys added with the Vive, not 13 (the last one on the other side doesn't match): https://backpack.tf/profiles/76561197999873164#!/compare/1505520000/1505606400 - So your sale comes out to 75.5

Another Casemaker sale: https://backpack.tf/profiles/76561198060802427#!/compare/1511568000/1511654400 - W/ ~15 for Blizzardy Vive, ~65 total

Can round this to 65-75.
