These 4 sales are the only sales that were made in the last 3 months. The sale at 29 looks like a clear outlier to me. The other sales were at 21 or below. The sale at 16 is not a quicksell in my opinion since it took him 5 days while advertising in trade servers a lot.
Going with 16-21 keys as a range.
