Dumped to a scrapyard bot, untrace? Someone then bought it and instantly listed it on Mannco.Store but impossible to know who it was.

I'll also note that one sold via an auction for 19 keys (sale 10) https://scrap.tf/auctions/VMEP32

Sales:

16, 19, 20, 21, 28

Sellers:

BPTF - https://imgur.com/v1lABDw 30 keys (1 month), buyers at ~20 keys

MPTF - https://marketplace.tf/items/tf2/30362;5;u59 $53.99 (~29 keys)

STN - https://stntrading.eu/item/tf2/Unusual+Aces+High+Law none, buy order at ~20 keys

SCM - https://steamcommunity.com/market/listings/440/Unusual%20Law?filter=Aces+High https://imgur.com/MNsAEO1 none

16 and 19 are definitely low given the buyers at ~20. I would call 20 low too but having 2 lower sales already excluded makes me feel like a lower low end is justified. Going with 20-28 keys
