MtM mini:

Ideally want to use a contemporary sale because of how taunts are dropping, though because its a halloween effect it might be alright.

Sold for SGG MtM (Outdated at 43, currently a 2-month unsold at 39, going to Micro, Micro at 30)

https://marketplace.tf/items/477;5;u3014

Sold for $90

Marketplace keys at ~2.05, = 44

Taking 30-44, seems fairly volatile and that value is the best representation of that.

Let it ride.
