https://backpack.tf/item/6818994882 - 170 keys

Screenshot taken from the cached page 7 days ago, which shows it being listed at 170 keys 9 days ago.

Sale at 175.

Regardless of the 170 key seller being listed at the same price a week ago, it does seem like a fairly inactive listing. It’s also fairly close to what we already have, so it shouldn’t matter too much if we exclude it.

Going with 175 flat.
