Haunted Ghosts Law sold for (Duped) Chiroptera Venenata Powdered Practioner, Aces High Hunter in Darkness, MONOCULUS! Strangifier, and Noise Maker - Crazy Laugh

Hunter in Darkness is in-date at 31 keys.

Noise Maker is outdated, but he is selling it for 4 keys on classifieds unsuccessfully for 2 months.

Taking Monoculus Strangifier as 16 keys.

Haunted Ghosts Law is currently being priced at 180 keys.

https://backpack.tf/suggestion/5c8ad80bd381721b521a88d4

[practitioner] + 31 + 4 + 16 = 180

This makes the practitioner 129 keys, rounding to 130.

Even if the Noise Maker was 1 key, I would still end up rounding this to 130.

Sold for a clean Vintage Scrap Metal.

Vintage Scrap is currently being priced at 333 keys.

https://backpack.tf/suggestion/5c8aa28067807227d722ede2

Sellers:

There are two sellers for this hat, 200 and 250. Both sellers are selling the Duped version of this hat. I cannot find the clean version anywhere.

https://gyazo.com/8e8a872deb40377a32ceb309f1e40021

Safe to say that 333 keys is an outlier.

Going with 130 keys.
