both compares on seller's side match, buyers showing 250 leaving as well, making it 250 keys.

Item 2:

https://backpack.tf/item/14043822695

No sale, bunch of swapping in between accounts to prepare for a tradeup "event" (exchanging skins of the same collection + sending the item to Milker, who's hosting the tradeup)

You won't see anything really match besides a 1/1 for a SFN Treadplate between Milker and me. Since we did not really give them a value besides "same collection, same wear, burning it anyway later" I would argue that it can be ignored + the treadplate is outdated as well. (probably cant be used to update treadplate sadly)
