This one is a doozy for me.

I literally gave myself a headache over the evidence.

Three traceable sales. Determined the third sale is an outlier.

Considering an outlier. Sole Mate was Pro KS, unable to find a down-to-earth mini for it, and the mini found would push this over 200 keys.

Mini: Anger: - Sold for an Aussie Scattergun w/ Parts

Concluding on 33 Keys.

Mini: Guadalajara: - Sold for Purple Confetti Hot Rod

http://backpack.tf/profiles/76561198197305249?time=1435215600

http://backpack.tf/profiles/76561198197305249?time=1435302000

Concluding on 21 Keys.

The mini found on the Sole Mate was over 150 keys (with uncertainity of how much more was added). 40,65, 180. 180 is a definite outlier.

Keeping the raw range on this. No way to rounding the range without some drop in median.
