No recent sales on marketplace, so it wasn’t a marketplace sale.

Sales at:

30

35

No current sellers.

The sale at 35 (Sale 1) re-sold to a quickbuyer for much less (Sale 4). Excluding 35.

Quickbuyers are up to 28 keys, however, given common b/o’s for less than the next highest value (30), and the fact that this item went to quickbuyers several times (some of the trades being untraceable), 28 shouldn’t be excluded. We can exclude 27, however.

https://bot.tf/stats/listings/Y31NW50M - 2 sellers for less than 29 at one point (from sale 3’s b/o)

Going with 28-30.
